SmartForm 11.7 Design Guide 1 Edition 2 Jan 2012
Description
SmartForm 11.7 LVL is a Douglas Fir structural laminated veneer lumber (LVL) manufactured by Pacific Woodtech Corpora on, Washington State, USA to meet the quality controlled process requirements of AS/NZS 4357 - Structural Laminated Veneer Lumber. It is produced in industry standard sizes, painted safety yellow for easy visual iden fica on, and is intended for use as concrete formwork support structures such as joists, bearers, walers and soldiers.
Quality
Compliance with process based quality control requirements is third party audited by SAI-Global, and the audits, together with end product tes ng is used as the basis for Product Cer fica on by SAI-Global as a JAS-ANZ ac-credited Product Cer fica on body.
JAS-ANZ stands for the government established “Joint Accredita on System of Australia and New Zealand” which exists as the peak organisa on for accredita on of Product Cer fica on bodies.
Marking
Each piece of SmartForm 11.7 is branded at least once with the SmartForm branding compliant with AS/NZS 4357 structural LVL standard for iden fica on and evidence of compliance with
manufacturing control standards and product quality cer fica-
on. It is also sealed with a water resistant yellow coa ng to increase its durability, providing the user with extended lifecy-cles and superior performance.
Scope of these tables
This Design Guide and load tables assist in the selec on of SmartForm 11.7 formwork materials in standard applica ons. All load tables in this document are developed using in-grade test-ed characteris c proper es of SmartForm 11.7 as distributed by Tilling Timber. Other look-alike subs tu on LVL formwork prod-ucts manufactured by different producers may have different proper es, and their specifica on from these tables may create an unsafe support system or unsa sfactory performance. This publica on is therefore strictly limited to the design of joists and bearers in common formwork applica ons. Reference should be made to AS 3610-1995 plus supplements 1 and 2 and an experienced structural engineer for methods and details of developing lateral restraint, providing suitable ver cal support to joists and bearers in the above tables as well as the robust-ness and stability of the formwork system as a whole.
Technical Support
This Design Guide covers only the most common formwork ap-plica ons. For applica ons, service classes not covered in this Design Guide and/or general product enquiries about Smart-Form 11.7, please contact SmartFrame technical support on 1300 668 690 or at smartdata@ lling.com.au

Rigidity EI x 109 Nmm2
The design of formwork always starts with defining the quality of the finished concrete surface. This is usually communicated through the project documents. Surface quality is effected by the extent to which the formwork components deflect under the applied loadings. Physical quality and tolerances, detailed in AS 3610 tables 3.3.1 and 3.4.2 guide the formwork designer in the selec on of formface material and deflec on limits for the framing members for soffits and wall forms. The tables include the deflec on criteria for the most common classes of finish, namely: Class 3 - Maximum of 3 mm or span/270
Span tables for alterna ve deflec on limits are available by contac ng the SmartData Customer HelpLine on 1300 668 690 or at smartdata@ lling.com.au The design aids in this design guide are confined to the selec-
on of SmartForm 11.7 LVL members which ensure that the formwork provides the strength and rigidity necessary to meet both structural safety and surface quality requirements. Struc-tural safety is limited to the selec on of individual structural components subject to normal concrete pressures. This design guide does NOT address the structural safety of the system that may be subject to a wide range of abnormal and acci-dental loads. Methods for developing lateral restraint, provid-ing adequate support as well as the overall stability of the structure are outside the scope of this publica on. The members in this table have been designed based upon the addi on of the “Global load factor for primary member” intro-duced into AS 3610 - 1995 with Amendment 1 - 2003. For horizontal members such as bearers and joists for soffits, both the joists and bearers have been considered primary members. For ver cal forms, the soldiers have been consid-ered primary members.

SmartForm 11.7 - “F” grade timber comparison
LVL is an engineered mber product whose characteris c strength proper es are derived by in-grade tes ng to AS/NZS 4063. “F”” grades are assigned a er visual grading of the solid
mber to the appropriate standards.
There is no direct link between “F” graded mber and in-grade tested mber.
Notwithstanding the above, SmartForm 11.7 may be used to safely subs tute “F” graded material up to and including F8.

Notes for use with Table
1. Minimum bearing length = 45 mm at end supports. Subscript values indi-cate addi onal bearing length re-quired above the minimum of 45 mm to achieve the stated span
2. Spans in tables have been designed as per sec on 4 of AS 3610-1995, includ-ing Amendment 1:2003 for all stage 1, 2 and 3 loadings. This allows for a 4.0 KPa imposed load due to stacked material as a stage 3 loading. This load is considered to be addi onal to other live loads. If the project designer ap-plies limita ons to restrict these mate-rial loads to a lesser amount (as speci-fied in Clause 2.3(b) of AS 3610 - 1995), then larger spans will be achieved.
3. Since the finish quality is dependent upon a number of factors including the formface used and the accuracy of the setup, a class 3 finish cannot be guaranteed.
4. For mul ple spans, the design has assumed the most conserva ve of 2 and 3 spans and that all spans are essen ally equal.
5. The design has assumed that the joists are con nually restrained by the shee ng and the bearers are re-strained by the joists.
6. The design tables are only suitable for horizontal forms. For angled soffits, consult a formwork designer.

6. The design tables are only suitable for horizontal forms. For angled soffits, consult a formwork designer.
7. To sa sfy the bearing requirements of the mber, the breadth of the bearer must be equal to or greater than the breadth of the joists it is suppor ng.
