Problem Description
This error affects flexural capacity calculation of single angles (both equal and unequal).The CSA S16-09 and S16-14 specifications, does not provide specific guidelines on the determination of the bending capacity of single-angle sections. In absence of such guidelines, STAAD.Pro uses corresponding expressions from Clause No. F10.2 of the AISC 360-05 (for CSA S16-09) and AISC 360-10 (for CSA S16-14) codes, for the evaluation of the bending capacity of single angle sections. However due to a coding error, the expression was improperly implemented in the program, due to which the bending capacity was being over-estimated leading to an unconservative design of angle sections.
