摘要：
In order to study the lateral resistance of steel frame structure built in traditional style, low-cyclic reversed test was carried out on a model of 1/2 scale one-storey and two-bay steel frame structure built in traditional style. Based on the testing results of displacement angle and bearing capacity under lateral forces, the researches about loading mechanism and seismic behavior of the steel frame structure built in traditional style were studied, the structural elastic-plastic characteristics, the lateral stiffness of overall frame, stiffness degradation regulations under the same-displacement cyclic loading and relationship between displacement and residual deformation were analyzed. The results show that the steel frame structure with traditional style has high bearing capacity and lateral stiffness, multiple seismic fortification lines is formed under the action of horizontal load, the structural stiffness degradation shows a fast to slow regulation. The sharp drop of bearing capacity doesn't appear and the displacement angle reaches 1/20.The beam-hinged failure mechanism is realized, which satisfied the seismic design principle of strong column-weak beam, strong core zone-weak members. © 2019, The Editorial Board of Journal of Basic Science and Engineering.
