摘要
对框架-带缝钢板剪力墙试件在恒定竖向荷载作用下进行低周往复水平加载试验,研究其抗震性能,并考察框架底梁不同边界条件对抗震性能的影响。试验结果表明:框架与带缝钢板剪力墙协同工作性能优越,有限竖向荷载及框架底梁对剪力墙的不同约束条件对剪力墙受力性能影响不大。有限元分析表明,较大竖向荷载对剪力墙受力性能可能有一定的不利影响,并给出了竖向荷载限值。通过有限元模型分析研究了框架和带缝钢板剪力墙的协同工作性能,提出了剪力墙先行屈服且充分发展耗能能力的设计原则应为结构层中剪力墙屈服承载力之和与其刚度之比小于框架系统的该比值。
Two assemblages of steel plate shear wall with slits （SPWS） together with its surrounding frames were tested under cyclic horizontal load and constant vertical load, and the influence of different boundary conditions of the frame bottom beam on the seismic performance of SPWS was also investigated. The test results show that the presence of finite vertical load and different boundary conditions of the frame bottom beam do not affect the performance of SPWS, the synergistic effect for frame and SPWS is quite noticeable. Finite element analysis on the sole SPWS indicates that with the increase of vertical load, the behavior of SPWS shall be degraded, thus a recommendation is put forward for the limitation of vertical load on the SPWS. The synergistic effect for frame and SPWS was further studied according numerical FEM computation. The design rules for ensuring that the yielding of SPWS precedes the yielding of frame members as well as the sufficient dissipate energy were proposed.
