Civil 2017 (v3.1) Release Note Civil 2017 Analysis & Design

1. Plate Beam and Plate Column (1D) Design Method

Plate elements can now be designed with the same method of designing conventional 1D elements such as Beam or Column as per AASHTO-LRFD12.

The plate design is performed for defined sub-domain. Member Type are chosen according to the purpose of the design (e.g. Plate Beam (1D) : Slab Design and Plate

Column (1D) : Abutment Design). Rebar Direction for the main rebar and distribution rebar can be defined using Local Coordinate System, UCS or Reference Axis.

Define Domain Define Sub-Domain

* Note : This feature is used for the calculation of Wood-Armer moment of specific direction. This will be fixed to default for Plate Design (Dir.1 = 0 deg, Dir.2 = 90 deg).

1. Plate Beam and Plate Column (1D) Design Method

The results of plate design can be checked in table format and also both Graphic and Detail report can be outputted.

Positive/Negative Bending moment capacity, shear capacity and crack checks can be performed and the detail results can be obtained from this function.

The main target of this function is culvert and abutment. Axial force is not critical when we are designing culvert or abutment. Therefore this feature does not consider

the benefit of axial force in calculation of flexural strength. However the calculation of axial resistance is provided in checking mode.

Top and Bottom rebar data can be inputted separately for multiple locations.

Rebar can be inputted using either Number or CTC method.

The amount of rebar (As) is shown directly.

2. Plate concurrent forces for Moving Load & Settlement analysis

Concurrent forces for moving load & settlement analysis are now available for following codes:

[AASHTO Standard, AASHTO LRFD, AASHTO LRFD (PENNDOT), Canada, BS, EUROCODE, Australia, Poland, Japanese, Taiwanese and Korean].

In the previous version, concurrent forces were available only for beam elements. In order to obtain concurrent forces for plate elements, the users needed to convert

moving load case into static load case using Moving Load Tracer. In the new version, by selecting [View by Max Value Item] in the context menu of Plate Forces Table,

concurrent forces can be checked in the result table without converting them into static loads.

3. Concrete damaged plasticity model

It is possible to describe the following behavioral characteristics by using Concrete damaged plasticity model.

• Application of different yield strengths in both tension and compression.

• Degradation effect of different elastic strengths in both tension and compression.

• Stiffness restoration effect under cyclic loading.

5. South African Moving Load TMH 7: Part 1&2 provide very specific guidelines for moving load applications, especially based on the influence line theory.

NA load is applied as nominal distributed lane load and nominal axle load. The loaded length increment for NA vehicle could be controlled by the user for faster or

more accurate analysis.

NB24 and NB36 vehicles as well as NC vehicle with width provisions of 3m to 5m and an option whether to consider the relieving effects or not is also introduced.

Besides the standard vehicle, user defined vehicles could also be defined by editing the standard vehicles, or consider a completely different vehicle load by means of a

Permit truck.

Provision for moving load combination as per the code as well as for special bridges (like multi-level) are implemented and concurrent reactions & forces could also be

obtained.

6. Export Centrifugal, Acceleration & Braking forces (EC & BS)

It is possible to export coincidental centrifugal, acceleration & braking forces according to the Eurocode and British Standards (BD 21/01 & BD 86/11).

It is possible to import vertical, centrifugal (C), acceleration ( Longitudinal – AA & Transverse – AL) and braking ( axial – BA & lateral – BL) as different static load cases.

7. Option to view Eurocode Live Loading with or without ψ factors applied

Visualization option in Results > Moving Tracer enables to show Eurocode vehicle live loading with or without applied ψ factors.

This option is applicable for all relevant Standard and User Defined vehicles under the Eurocode Moving Load Code.

Ignore ψ Factor option must be checked off in the Moving Load Case for the option to take effect.


Example Load Model 1 without ψ factors Example Load Model 1 with ψ factors

* Note : The option will only be available for Moving Load Cases with Ignore Psi Factor checked off. This option to view ψ factors will NOT affect the analysis results

(including exported results using Write Min/Max Load to File) which will include the ψ factors.

9. Addition of SV-TT Vehicle and Correction of Wheel Spacing According to BD 86/11

Previously wheel spacing of SV, SV-Train, and SOV vehicles were modelled by 4 equidistance wheels.

In the new version, SV-TT vehicle has been added along with the corrected wheel spacing of all vehicles as defined in BD 86/11

10. Improve method of Settlement & Specified Displacement of Supports constraints In the previous version, when settlement load cases or specified displacement load were applied to some nodes, the corresponding nodes behaved like

fixed support even for other load cases that did not contain specified displacements. In Civil 2017 (v3.1), only the nodes to which specified displacement

load case or settlement load case are applied will behave like fixed support.

ength and Serviceability Limit State are updated with respect to latest IRC 6: 2016

The Orientation option is now activated to change a local axis of ‘Plate’ and ‘Plane Stress’ element type.

Previously, plate local axis can be modified in post-processing mode using ‘Plate Local Axis in Results tab. This function is no longer available since new feature can re

place the previous feature.

2. Import & Export of Nodal Results (GTS NX)

This feature allows to import and export the nodal results for nodes with defined constraints.

For exporting feature, users can opt to export results at all constraint locations or at selected constraint locations. Additionally, users can select the analysis set, step

(construction stage), result type (reaction or displacement), and result component for output.

The development allows users to import nodal results from both midas Gen or Civil.

Reactions will be imported as Nodal Forces (FX, FY, FZ) and Moments (MX, MY, MZ) and Displacements will be imported as Prescribed Displacement (Tx, Ty, Tz)

excluding rotation.
