英文摘要：

The application of high strength steel in angle tower structures can reduce the structure weight and cost, save energy, protect environment and achieve good economic and social benefits. In the paper, recent researches on stability behavior of main members con- nected to high strength steel angle tower with two legs were comprehensively reviewed. The influence factors and causes of stability per- formance also were studied, including the initial residual stress of high strength steel, steel strength grades, the local buckling perform-ance of plates, the end restraint, and the correlation influence between plate local buckling and the overall instability of compression member. It may provide a reference for both relevant investigations and proposal of design idea.
