[Abstract]:Since 2013, China's steel production at 779 million tons ranked first in the world. Steel frame structure has been developed in more and more fields. As a key point in steel structure design, many scholars at home and abroad have carried out a series of research and put forward many types of steel joints. Round steel pipe column is widely used in architectural design because of the same moment of inertia in each direction, high economic benefit, convenient construction and excellent seismic performance. Yunnan Province is located on the Yunnan-Guizhou Plateau, the mountain area is rough and earthquake prone, and the steel transportation and installation conditions are relatively poor. Based on the geological and geomorphological situation of Yunnan Province and the existing research results of experts and scholars at home and abroad, In this paper, a new type of joint, which is convenient for site installation and transportation, is proposed, which is a split type steel tubular column H-type steel beam joint with outer sleeve. The reciprocating cyclic loading test is carried out on this joint, and the test results are analyzed. The load-displacement curve during loading and the influence of parameters on the performance of the specimen are studied. At first, three steel tubular column H-type steel beam joints with cross-shaped outer sleeve were made to carry out cyclic loading tests on the end of the beam respectively, and the deformation at the joint of the three members and the failure of the flange of the beam were observed and recorded during the loading process. The load-displacement hysteretic curves, stiffness degradation and joint energy consumption of each node are analyzed, and the effects of sleeve thickness on the joints' mechanical performance are compared and analyzed by using ANSYS 15.0, a finite element software, is used to model and analyze the new type of joints studied in this paper. By comparing the test results with the finite element analysis results, the reliability of the ansys software is proved. The influence of the parameters of the new type outer sleeve joints on the performance of the joints is analyzed, and a formula for the design of the minimum thickness of the sleeve is put forward for the reference of the subsequent design and the theoretical researchers. At the end of the paper, a design table is put forward for the design of the steel joint.
