传统风格建筑钢框架结构拟静力试验研究
Quasi-static test on steel frame structure in traditional style buildings
摘要
Abstract
In order to investigate the seismic behavior and failure mode of steel frame structures of traditional style buildings,the low cyclic reversed loading test was carried out on a 1 ∶ 2 scaled model of a steel frame structure of traditional style building built in the areas with a seismic design intensity of 8 degree.The failure process and patterns of the structure were observed.The mechanical behaviors such as load-displacement hysteretic loops,skeleton curves,strain characteristics,ductility,energy dissipation,stiffness degradation and load bearing capacity degeneration of the frame were obtained.Test results show that the Dou and Gong components of the Chinese traditional style steel frame structures act as the first seismic line under the action of horizontal load,the plastic hinge at the beam end develops fully and the seismic design principle of ‘ strong column-weak beam,strong core zone-weak members’ is satisfied.The pinching phenomenon of hysteretic loops appears,and it is Z-shaped,indicating shear-slip property,which shows obvious difference compared to conventional steel frame.The stiffness degradation of the structure is significant at the early stage of the loading.At failure,the ultimate elasto-plastic drift ratio and the bearing degradation coefficient is 1/20 and 0.9,respectively,indicating the excellent collapse resistance capacity and stable load bearing capacity of the steel frame structures of traditional style buildings.关键词
