足尺带缝钢板剪力墙低周往复加载试验研究Ⅰ
|
摘要
在有限元分析边界约束对带缝钢板剪力墙性能影响的基础上,设计加工了一套带有连杆机构和侧向支撑从而能较好模拟框架梁对钢板剪力墙面内转动及端部侧移约束状况的试验装置。通过该装置完成了2个足尺带缝钢板剪力墙试件的低周往复加载试验。为了防止带缝钢板剪力墙过早失稳,试件在纵向边缘以方钢管进行加劲。通过试验考察了带缝钢板剪力墙的受力特性及破坏模式。试验结果表明:试件因实现了屈服后屈曲从而具有较好的变形及耗能能力;构造上采用方钢管加劲是可行的。试验同时暴露了试件出现的"角部失稳"和"螺栓滑移"等问题,并为这些问题的解决提供了有益线索。
Based on the analysis of boundary conditions' effect on behaviors of steel plate shear wall with slits(SPWS) by finite element software,a set of test apparatus which included linkage mechanism and lateral supporting systems were designed and fabricated.This test apparatus can approximately reflect the frame beam's restraint on SPWS.Two full-scale SPWS specimens subjected to low-frequency cyclic loads were tested successfully.In order to prevent the occurrence of instability in early loading stage,steel tube was used as longitudinal brittle stiffener of specimens.Through the test,the mechanism character and failure modes of SPWS were investigated.Test results indicate that the specimens exhibite yielding adequately before buckling resulting in considerable capacity of deformation and energy dissipation.The test also exposes two problems of 'corner instability' and 'bolt slip' and provides key clues to solve them.
