钢板剪力墙-框架相互作用性能

在侧向荷载作用下,考虑填充板和框架杆件之间的相互作用,研究了钢板剪力墙双体系的非线性性能。对多组钢板剪力墙试件进行数值分析,研究填充板对框架性能的影响,评估其抵抗侧向力的有效度。结果表明:按规范设计的钢板剪力墙具有理想的屈服顺序,填充板首先进入塑性。这说明:填充板在加载初期非常有效,转角可达到1%,承担了大部分层间剪力。然而,一旦填充板中屈服区域继续发展,它们将逐渐失效;当屈服区域延伸至墙体,附加荷载将基本上由框架杆件承担。

Characteristics of the Wall-Frame Interaction in Steel Plate Shear Walls

The nonlinear response of steel plate shear wall(SPSW)dual systems under lateral loading with regard to the interaction between the infill plates and frame members is studied.A number of SPSWs are numerically analyzed and the results are utilized to discuss(a)the influence of infill plates on the behavior of frames and(b)to evaluate their degree of effectiveness in resisting lateral loads.Results show that SPSWs designed according to design codes should have desirable sequences of yielding and that plastic ...
