Abstract：Combined with the stress characteristics of the welded joints of the steel tubular truss in the real construction, the MSC.Marc software is used in the finite element model to establish the solid model to conduct the static loading test and study the stress performance and the changing condition.The finite element analysis of the stress distribution is made in the loading force of the welded joint of the sample.Then, the theoretical result of the finite element calculation is compared with the obtained test results to verify the correctness of the design.The test results show that the joint is stronger than the connected pole and is enough to meet the stress requirement of the overall structure, also the finite element analysis matches the test well, but the regional stress of the joint is more complicated and the stress concentration is more obvious.
