摘要

Lattice towars made of hot rolled steel angle sections are used to support transmission lines and radio antenna. The legs of these towars are usually strengthened by retrofitting extra parallel bracing members. This paper presents a numerical method for predicting the failure load of sinlge and compound angle sections used in steel towars considering second order and inelasticity effects. Predi tions from the method are compared with limited labroatory results.
