    DELTABEAM

    1. DESCRIPTIONOF THE SYSTEMDeltabeam is a hollow steel-concrete composite

    beam made rom welded steel plates with holes in

    the sides. It is completely flled with concrete ater

    installation on site. Deltabeam acts as a composite

    beam with either hollow-core, composite, or thin

    shell slabs, and in-situ casting. Deltabeam can

    have a fre class rating as high as R120 withoutadditional fre protection.

    5. APPLICATION

    5.1 Limitations orapplication

    The bearing capacities o the Deltabeams have

    been calculated or static loads. Greater partial

    saety actors must be used or dynamic loads and

    atigue loads on a case by case basis.

    5.2 Design principles

    Figure 4. Minimum

    distance of web holes from the end of the beam

    The shear joint between concrete and steel beam

    is ormed by the dowel action o the web holes lo-

    cated in the web o the beam. Static loading tests

    have proven that the interaction rate is complete.

    The flling cast unctions as cross-section compres-

    sion components in the fnal structure. Transverse

    reinorcement is described in fgure 5, the reinor-cement is anchored rom the end o the slab over

    the length o the anchoring zone o the beam. With

    hollow-core slabs, the location o web holes is

    adjusted to the joints between the slab elements.

    Figure 5. Minimum transverse reinforcement

    Figure 6. Length of Deltabeam supporting ledge.

    The bearing support distance (to hollow-core

    slab or other deck) may vary rom standard

    requirement, see fgure 6. I the bearing support

    distance is shorter than shown in fgure 6, Peikko

    Finland Oy must be consulted. Using smallerbearing surace impacts the design, dimensioning

    and cost o Deltabeam.

    Selection o oor structure

    Cost comparison

    Selection o beam type and joint details

    Floorplans with load data and cross-sectional

    drawings

    2. Quotation phase

    Basic data: project oorplans and quotation or the

    project (loads, perorations, fre protection rating,

    exural limits, surace treatments)

    Preliminary dimensioning o beams to the project

    Implementation plans

    Marking o beam identifcation codes to oor

    drawings*

    Installation plan (including supporting plan)

    4. Beam strength calculation

    Complete basic project in paperwork is copied and

    sent or e-mailed to Peikko Finland Oy Deltabeam

    Beam strength calculations and structural drawings

    to the chie structural engineer/customer

    Beam data or the hollow-core slab designer

    Installation instructions o the beams to the

    customer

    *each beam has unique identifcation code

    Peikko will carry out detailed project-specifc measuring in the implementation phase. Then, the unctional

    and ultimate strength properties even in case o fre are checked. Also the required pre-cambering o the

    beam is defned. Deltabeam is designed to ensure hollow-core slabs require no additional support or props

    during installation.

    www.peikko.com

    5.2.2 Selecting the Deltabeam

    profle

    The preliminary selection o beam type is madeon the basis o tables 1 and 2 (page 5) and the

    bearing capacity curves / pre-selection sotware.

    The pre-selecting sotware can be downloaded

    rom Peikkos website www.peikko.com.

    The height o the Deltabeam can be 185 - 500 mm.

    Maximum length is 12,9 - 13,4 m depending on

    used plate material.

    It is more economical to use Deltabeam or the

    short chord and slabs in the direction o long

    chords.

    Intermediate beams (D)A site-specifc special

    type can be used i

    necessary. The width

    and/or height o the

    special type departs

    rom the normal

    dimensions. I Inter-

    mediate beams are

    used as edge beams with ormwork sheet, then

    the fre protection o the ree side is covered with

    concrete.

    Edge beams (DR)

    The Delta edge beam is

    designed to serve as a

    slab edge beam when a

    narrower Deltabeam is

    needed and the vertical

    side is protected rom

    fre by other structures.

    The edge beam can also be used on aperture

    edges, which usually require separate fre protec-

    tion or the vertical web. The need or fre protec-tion must be determined on a case-by-case basis.

    Width is determined on a case-by-case basis.

    Beam ledge height may be varied to accommodate

    diering slab profles (see fgure 8).

    Figure 8. Deltabeam with elevated ledge (left) and with

    formwork sheet (right).

    5.2. Connection details o

    Deltabeam

    The structural engineer designs the connectiondetails o the beam. The connection must be

    designed in a way that the support reactions

    o the beam are transerred to the supportive

    structure (e.g. column, wall or another beam). This

    supportive structure must be designed to bear the

    orces rom the beam. In columnbeam joints, it

    is recommended to use the PCs corbel designed

    especially or the steel beam.

    Stress and torsion during installation must be

    taken into account when designing the joint detail

    and supportive structure.

    Indicative connection

    details are described in the

    Deltabeam design older

    and on Peikkos home page

    at www.peikko.com.

    The bottom plate can be

    cut at the end o the beamaccording to the joint detail

    o the project and the data

    sheet o the beam to be,

    e.g. skewed or arched.

    This way, the appearance

    o the connections will be

    fnished.

    Peikko sizes the beam

    according to the joint

    details. Peikko also

    designs the internal beam

    connections (cantilever andside joints).

    5.2.4 Expansion and working joints

    o the slabs

    A transverse expansion joint is built into the

    console coupling by encasing the inside o the

    beam end joint to it so that there is room or

    movement ater casting. A longitudinal expansion

    joint is placed at the beam ledge.

    Working joints are placed on a case-by-case basis

    so that they can be taken into account when

    perorming strength calculations.

    5.2.5 Voids and joints

    It is preerable to have all perorations and voids

    made at the actory. Machining o the beam

    is perormed by ame cutting or drilling. The

    structural engineer marks the inormation on voids

    and joints to the data sheets. Peikko must always

    be contacted i any changes are to be made.

    All on-site connections in the beam are to be

    installed in compliance with the instructions given

    by the structural engineer. I additional connections

    are required, Peikko must be contacted.

    5.2.6 Supporting beams during

    installation

    The structural engineer makes the installation and

    supporting plans or beams. Due to its box-like

    structure, the Deltabeam is capable o transerring

    the stresses o an eccentric load back to the co-

    lumn. I the installation plans dont tell otherwise,

    Deltabeam has to be always supported.

    The installation support is located at the end o the

    beam on the load side, near the web and bottom

    plate joint. Supports can only be removed when

    the slab cast and beam infll is cast have ully

    hardened.

    I a Deltabeam is

    bearing on the endo a wall, the beam

    must always be

    propped until the

    concrete has been

    matured.

    When the Delta-

    beam is used to

    transer oor loads

    to a wall-type beam,

    the beam must be kept ree rom loading until

    the installation/casting o the intersecting oor is

    complete. Installation supports cannot be removed

    until the upper wall is capable o bearing the ull

    oor load.

    5.2.7 Fire protection and

    environmental classes

    Rebars installed inside the beams at the works and

    webs act as load-bearing structure in the event o a

    fre. In the design phase, the beam is dimensioned

    in compliance with the fre class rating o the

    building, and rebars are used when needed. The

    fre rating o Deltabeam is based on combustiontests and the dimensioning guidelines obtained

    rom them. Deltabeam can have a fre class rating

    as high as R120 / R180.

    Edge beams (DR)

    The vertical side o the edge beam must be

    protected rom fre by other structures or

    materials/fnishes.

    5.2.8 Surace fnishings

    The Deltabeam is rust-prooed or hot-dip

    galvanised. State-o-the-art surace coatingtechniques also ensure surace durability during

    transport and installation. When the underside o

    the beam is fnished in the same way as the slab,

    the Deltabeam can also be let exposed, i desired.

    6. INSTALLATION

    6.1 DeliveriesDeltabeams are delivered to the site according

    to agreed project schedule. Beams o dierent

    lengths cannot be loaded at the actory in order

    o installation. The beams are marked with

    identifcation codes in accordance with the

    drawings.

    6.2 Storage on site

    Deltabeam parts that remain exposed are painted

    with corrosion protective primer. In long-termstorage, the beams must be covered. Struts are

    used under the beams to protect the painted

    suraces. When storing beams in piles, the

    load-bearing capacity o the oundation must be

    checked.

    6. Liting and moving

    When erecting, it has to be observed that the

    beams are installed in the same direction as

    marked on element chart.

    Beams can be lited and moved using ordinary

    liting equipment, cranes or orklits. The beamsweb holes serve as attachment points or liting

    lugs. The weight o the beam is marked on the

    beam label.

    6.4 Installation

    Beams are installed according to appropriate

    installation plan. The beams are installed in a waythat the identifcation codes read in the same

    direction as marked in element chart.

    Figure 10. Element chart

    6.4.1 Beam fxing

    Connection details are specifed in the structural

    plan in a project-specifc way. The supplies needed

    or internal beam connections (cantilever and side

    connections) are included in the delivery.

    All beams must be

    fxed beore slabs

    can be installed. This

    way movements o

    the beams can be

    prevented. Beams

    weight is not eective

    enough to stabilize the

    rame during installation

    o the slabs.

    6.4.2 Supporting the beams

    The beams are supported beore installing the

    slabs in compliance with the installation and

    supporting plan made by the engineer. See chapter

    5.2.6.

    6.4. Installing the slabs

    All beam support and asteners indicated in the

    plans must be securely installed, tightened or

    welded beore the installation o the slabs. Ater

    the slabs are installed, the necessary ormwork,edge orming and slab reinorcement will be

    carried out.

    Every join between the slabs must be reinorced

    with minimum o M15 rebar.

    The width o the supporting surace is in

    compliance with the instructions o the supplier o

    the hollow-core slabs.

    Figure 11. Position of the

    end of a hollow-core slab in relation to Deltabeam

    Hollow-core slabs

    The elements are installed directly onto the beam

    ledge.

    Thin-shell, composite and in-situ cast slabs

    The composite steel sheet and thin-shell slab are

    installed directly onto the beam ledge. The com-

    posite sheet is supported at the same elevation

    as the beam. No room or settlement should be

    allowed. Thin-shell slabs are supported at the same

    nominal camber as the oor. Deltabeams pre-

    cambering ensures the straightness o the beam

    ater casting. In-situ cast slabs are ormed at the

    nominal level. The base o the beam is at the same

    level as the underside o the slab. The ormwork is

    installed under the beam ledge

    6.4.4 Concreting

    Deltabeams are concreted in conjunction with slab

    casting or the joint casting o hollow-core slabs.

    Deltabeams flling casts are usually dimensioned

    at the same strength rating as the joint casts. The

    usual concrete grade is 30 MPa. The properties

    o mixed concrete are determined according to

    the project and methods used in compliance with

    the concreting plan. The Deltabeam must be cast

    completely in order or it to possess the properties

    o a composite beam. Casting must be perormed

    in one pour.

    Steps in concreting:

    Ensure that the

    ormwork and

    reinorcement

    are in place and

    clean.

    Filling is perormed by

    inserting a pipe into the

    beam through casting

    ports. Begin flling the

    beam rom the centre

    o the beam. The fll

    level o the beam can be

    checked through the air

    holes. Fill consistency

    can be checked using a

    vibrating poker.

    1.

    2.

    I there are any ormwork sheets on the edge

    beams, extreme caution must be taken during

    casting to avoid damaging or buckling the

    sheets when using a vibrating poker.

    7. THINGSTO DO WHENTOLERANCESARE EXCEEDEDChief structural engineer or element designermust be contacted, and correction has to bealways done according to correction plandone by chief structural engineer or elementdesigner.

    7.1 When the corbel is on

    too low level

    Chie structural engineer or element designer

    does the plan or correction with the

    consultation rom Peikko. Without a proper

    correction plan the beams end plate can not

    be altered or changed.

    Corbels height can be increased with steel

    plate or beams end plate can be changed.

    I the beam can be fxed according to

    original plans (bolts, welding), small (max

    10mm) height dierences can be leveled

    by welding plates on the top o the console

    tube.

    I corbels height is increased with steel

    plate, the corbels supporting surace

    must remain identical to original.

    Additional steel plates must be fxed by

    welding.

    I the dierence in height level is greater

    than 10mm, the beams end plate must be

    changed.

    7.2 When the corbel is on

    too high level

    Chie structural engineer or element designer

    does the plan or correction with the

    consultation rom Peikko. Without a proper

    correction plan the beams end plate can not

    be altered or changed.

    There are ew alternatives to fx this kind o

    problem. The link in the beams end plate can

    be cut higher, or the end plate can be changed.

    I the new end plate needs to be thicker

    than the original, Deltabeam may have to

    be shortened.

    1.

    It is also possible to design end plate,

    that is as thick as the original, but greater

    in height. This way shortening o the

    Deltabeam can be avoided.

    7. When the beam doesnt

    reach support point

    Deltabeam requires supporting surace defned

    in construction design.

    Chie structural engineer or element designer

    does the plan or correction with the

    consultation rom Peikko. Without a proper

    correction plan the beam can not be extented.

    I the required extension is 150mm or less,the extension can be made directly to the end

    plate, or new, stronger end plate can be made.

    I extending o the beam is not possible, a

    new Deltabeam with accurate length has to be

    made.

    7.4 When anchoring bolts

    dont meet bolt holes o the

    beam

    The bolt holes in top and bottom plate o the

    beam can be expanded in the direction o

    length, with the maximum actor o 1.5 (or

    example: 50mm to 75mm).

    The bolt holes cannot be expanded in the

    direction o width without permission rom

    Peikko. Doing this may require the beam to be

    strenghtened.

    To expand bolt holes located in the beams

    web, a permission has to be asked rom

    Peikko.

    7.5 When transverse

    reinorcement doesnt meet

    web holes

    The web holes (150 or 80) o the

    Deltabeam cannot be expanded.

    Transverse reinorcement cannot be omitted,

    and they must be anchored inside Deltabeam.

    Chie structural engineer or element desig-

    ner does the plan or correction with theconsultation rom Peikko. Without a proper

    correction plan new holes cannot be made to

    Deltabeams web.

    7.6 When tolerances o

    Gerber-joint are exceeded

    The tolerance in beams length or Gerber

    and side joint is +5 / -10mm. The connection

    is designed so that 5mm shim plate is set to

    every joint ater the Deltabeam is installed, but

    beore tightening o the bolts.

    Check i the shim plate is used in other joints

    o the beam line.

    By adding or removing the number o shim

    plates rom other joints within the allowed

    tolerances, it may be possible to solve the

    problem.

    The shim plates can be used or maximum

    thickness o 15mm.

    I the problem can not be resolved with

    the use o shim plates, the joint has to

    be re-designed, and the end plate o the

    corresponding Deltabeam must be changed.

    1.

    2.

    7.7 When the Deltabeam is

    too long

    The correction plan is always done by Peikko.

    Typical procedure is the ollowing: the end plate

    o Deltabeam is removed, beam is shortened and

    the end plate is welded to the beam according

    the instructions rom Peikko.

    7.8 When the length or

    position tolerances o

    hollow-core slabs all below

    or are exceededThe correction plan is always done by Peikko.

    The situation concerns the strength o the

    Deltabeam during installation, because the

    stress diers rom planned.

    Also the strength o the beam connections

    must be checked, because o possibly greater

    torsion.

    INSTRUCTIONS FOR FILLING IN THEDATA SHEETSThe data sheet must be made so that the beam code in the oorplan reads in the correct way.
