摘要
为研究传统风格建筑的抗侧力性能,进行了1榀单层两跨传统风格建筑钢框架结构的低周反复荷载试验.通过测试试件在侧向力作用下的位移角变形和承载力退化趋势,研究了传统风格建筑钢框架结构的抗震性能,分析了结构的弹塑性特征、整体框架抗侧刚度退化、结构在同级位移循环加载条件下的刚度退化规律以及加载位移与残余变形的关系.结果表明:传统风格建筑钢框架结构表现出较强的承载力和良好的抗侧能力,在水平荷载作用下,钢框架结构形成多道抗震防线,结构刚度退化表现出由快到慢的规律;结构破坏时位移角达到1/20,未发生承载力陡降的不利情况;传统风格建筑钢框架结构在水平荷载作用下形成梁铰破坏机制,满足规范提出的"强柱弱梁,强节点弱构件"的抗震设防要求.
        In order to study the lateral resistance of steel frame structure built in traditionalstyle,low-cyclic reversed test was carried out on a model of 1/2 scale one-storey andtwo-bay steel frame structure built in traditional style.Based on the testing results ofdisplacement angle and bearing capacity under lateral forces,the researches aboutloading mechanism and seismic behavior of the steel frame structure built in traditionalstyle were studied,the structural elastic-plastic characteristics,the lateral stiffness ofoverall frame,stiffness degradation regulations under the same-displacement cyclicloading and relationship between displacement and residual deformation were analyzed.The results show that the steel frame structure with traditional style has high bearingcapacity and lateral stiffness,multiple seismic fortification lines is formed under theaction of horizontal load,the structural stiffness degradation shows a fast to slowregulation.The sharp drop of bearing capacity doesn't appear and the displacement anglereaches 1/20.The beam-hinged failure mechanism is realized,which satisfied the seismicdesign principle of strong column-weak beam,strong core zone-weak members.
