Stability Bearing Capacity Analysis for High-Strength Angle Steel Members with an Eccentric Load at One End

Abstract:

Single-angle compression members with an eccentric load at one end were widely used in transmission towers, analyzing the stability bearing capacity become a very complex issue due to end restraint conditions and the impact of defects. Experiment method and analytical method were used to study the size of the stability capacity on four kinds of members, analytical method use energy relationship, the boundary conditions issue is simplified according to different end restraint capacity, and finally discuss the theoretical ultimate bearing capacity of the test members. Compared with the experimental results show that the elastic theory analytical solution overestimates the capacity of members, using experiment method can obtain more secure mechanical behavior of high-strength angle steel member with an eccentric load at one end.
