The necessity of the research on flexural behavior of tubular steel tubular cross-section joints and the current research status at home and abroad are briefly described. Taking a key project as the background, the experimental research on the flexural rigidity and bearing capacity of the cross-section joints was carried out. The design of the test scheme and the main test results are introduced in detail in this paper. According to the tests on the bending stiffness of joints under various load conditions, it is shown that under certain conditions, the joint can be regarded as a fully rigid joint, and the flexural strength of the joints can ensure the bearing capacity of the members fully use.
