摘要
利用ADINA有限元软件建立了具有不同参数的单层钢框架-带缝钢板剪力墙结构模型,并对其进行往复荷载作用下的性能研究,经对比分析选取了性能最优的模型。研究该模型在不同轴压比作用下的性能变化,并与相同尺寸的单层钢框架模型进行对比,结果表明:两种钢结构均具有良好的耗能性能;随着结构轴压比的增大,其滞回曲线越来越不饱满且侧移刚度、屈服荷载、屈服位移、破坏荷载退化较为严重;而钢框架结构随着轴压比的增大其性能下降速度快于钢框架-带缝钢板剪力墙结构。本文建立了10层钢框架-带缝钢板剪力墙结构,对其在9度罕遇地震作用下层间位移角进行了模拟分析,结果表明:钢框架-带缝钢板剪力墙结构在三种地震波9度罕遇地震作用下的最大层间位移角均小于《建筑抗震设计规范》中所规定的层间角位移限值,依然能满足"大震不倒"的设计要求。
Single story steel frame-steel plate shear wall with slits models of different parameters are built by ADINA finite element software. Under the action of reciprocation force,the performance of the model is studied,and then the model with the best properties is obtained. In order to study the performance of it,different axial compression ratios are applied to the single layer steel frame-steel plate shear wall with slits,and compared with the same size of the single layer steel frame models. The results show that both of the steel structure members have the merits of good energy consumption property. As the increase of structure of axial compression ratios,the hysteresis curves become not full,and yield load,yield displacement,and failure load degraded seriously. The performance degradation rate of steel frame structure with the increase of axial compression ratio is faster than the steel frame-steel plate shear wall with slits. Moreover a ten story steel frame-steel plate shear wall with slits model is built on the basis of ADINA finite element software,and the nonlinear analysis method is carried out to analyze the earthquake hazard displacement angle between layers of the model under seldom occurred earthquake of magnitude of 9. The results shows that the biggest displacement angle between the layers of the steel frame-steel plate shear wall with slits under the action of the three kinds of seismic waves is less than the limit which is stipulated in Code for Seismic Design of Buildings. It can still meet the design requirements of ＂no collapse under strong earthquake＂.
