The Static Analysis About Complicated-welded on Tubular Rectangle-joints JinFeng Jiao1, a, Han Wu1,b , XueDong Shi 2,c and HongGang Lei1,d 1college of architecture and civil engineering, Taiyuan university of technology, TaiYuan,ShanXi 2Taiyuan municipal engineering design and research institute, TaiYuan, ShanXi ajiaojf_1@126.com, b11243909@qq.com, c306262337@ qq.com, dlhgang168@126.com   Keywords: welding; tubular joints; static analysis; stress concentration Abstract.
Welded rectangular steel tubular joints have been widely used in large span complicated steel structure engineering .With the type of the joints and structural measures complicated, there is no suitable joints theory formula in design specifications.
Given the welded rectangular steel joints which had high precision assembly, small welding deformation and large carrying capacity, it is widely used in large span complex steel structure engineering.
