Abstract

Abstract

Experiment on bearing capacity of 48 Q460 high strength angle steel for compression members attached by one leg was carried out,the results of mechanical behavior and deformation for specimens were analyzed.The experiment result shows: the bending deflection of the angle occurred in a direction parallel to the connected leg,meanwhile,the twisting deformation occurred in a longitudinal direction of specimen.Most of small slenderness members were controlled by local buckling,and large members were controlled by overall buckling.Then compared with the experimental results and American Design of Latticed Steel Transmission Structures ASCE 101997 results,the results show experiment results are slightly larger than American ASCE 101997 results.Therefore,Q460 high-strength equal angle steel compression members attached by one leg can be designed using ASCE 101997,and the design is in favor of a security.
