双功能带缝剪力墙的弹性受力性能分析

双功能带缝剪力墙是根据抗震控制概念提出的一种新型剪力墙。为了解其受力性能，并为进一步的试验研究参数确定提供依据，利用有限元方法，对双功能带缝剪力墙进行了弹性受力分析，研究了其在弹性阶段的受力性能、特点和连接键参数的影响。分析结果表明，双功能带缝剪力墙在弹性阶段具有一定整体工作性能，侧移刚度比通缝墙明显提高。在连接键总长相等的情况下，设置多个短的连接键对提高侧移刚度和实现“双功能”控制作用更为有效。根据分析结果，提出了双功能带缝剪力墙弹性侧移刚度的计算公式。

Analysis of elastic behaviors for dual function slitted shear wall

Dual function slitted shear wall is a new type of shear wall proposed according to seismic control concept. To study the mechanics behaviors and determine the connector parameters for experiment, the elastic finite element method was used to analysis dual function slitted shear wall under elastic stage. The analysis results show that the lateral stiffness of dual function slitted shear wall is obviously enlarged by setting the connectors in the slits; the setting of several short connectors for same total length is more effective for lateral stiffness increasing and dual function controlling. Based on the analysis results, a calculation formula of lateral elastic stiffness was suggested.
