1985 AITC code implementation
STAAD’s Timber design module per the 1985 AITC code (Timber
Construction Manual, 3rd. Edition, 1985) allows design of Glulam
timber sections. It also conforms to the National Design
Specification for Wood Construction and Supplement (NDS) and
building codes like Uniform Building Code (UBC), Basic/National
Building Code and Standard Building Code. Some of the main
features of the program are:
1. This feature is for Glulam Timber only.
2. Code check and design of members as per TCM - AITC.
3. Design values for Structural Glued Laminated Timber tables
are in-built into the program. The program accepts Table no.,
Combination and Species specifications as inputs (e.g, 1:16F-
V3-SP/SP) and reads design values from in-built tables.
4. Incorporates all the following Allowable stress modifiers:
i) Duration of Load Factor
ii) Size Factor
