How does STAAD.Pro compute the Ky and Kz when Calculate option is chosen from within Design Parameters for AISC ASD code?
STAAD.Pro can calculate the effective length factor for steel members when design is carried out as per the AISC 9th edition code ( invoked by the command CODE AISC ). The procedure is documented as part of the software help section What's New? > STAAD.Pro 2006 Release Reports > STAAD.Pro 2006 Build 1001 Release Report > AD.2006.1 Features Affecting the Pre-Processor > AD.2006.1.8 Auto Calculation of Effective Length Factors of Members as per AISC Code.
The calculation of the effective length factor is carried out as per a paper titled “Compression Members” by George Tsiatas which can be downloaded from:
