摘要

为研究半刚接钢框架钢板剪力墙结构（Partially-restrained Steel Frame-Steel Plate Shear Wall）的抗震性能，利用经试验验证的双向等效拉杆模型分析了低周往复荷载作用下梁柱半刚性连接对强、弱框架SPSW结构滞回性能、承载力、刚度、耗能能力的影响。分析结果表明：SPSW结构的滞回曲线具有双重特征，当周边钢框架较强时，滞回曲线趋于饱满；当内填剪力墙板较强时，滞回曲线趋于捏缩。随着节点抗弯承载力的增加，强、弱框架的SPSW结构的滞回性能趋于饱满，耗能能力增强，水平承载力呈增大趋势，但对强框架SPSW结构的影响程度大于弱框架SPSW结构。节点抗弯承载力对强框架SPSW结构的抗侧刚度影响较大，对弱框架SPSW结构抗侧刚度影响相对较小。

Abstract

In order to investigate the seismic behavior of partially-restrained steel plate shear wall (Steel Plate Shear Wall

SPSW)

the effects of partially-restrained connection on the hysteretic behavior

lateral bearing capacity

stiffness

energy dissipation of SPSW with strong and weak steel frame were simulated under low cyclic loading via equivalent strip model that had been verified by experiment. The results show that hysteretic behavior of SPSW has dual characters. The hysteretic curves of SPSW with strong surrounding steel frame become fat

and the hysteretic curves of SPSW with weak surrounding steel frame become narrow. With the increase of the bending capacity of PR connection

the hysteretic curves of SPSW become fat gradually

and the capacity of energy dissipation and lateral bearing increase. However

the effect on lateral stiffness of PR connection of SPSW with strong steel frame is higher than the one with weak steel frame.
