短肢剪力墙轻板结构抗震性能的试验研究

选取某短肢剪力墙结构住宅建筑中典型一跨进行单层1∶2模型的抗震性能试验,比较分析了各种荷载下不同组件的力学性能,研究短肢剪力墙轻板结构中轻质隔墙板对整体力学性能的影响。试验研究表明,与未加轻质隔墙板和普通钢筋混凝土板的短肢剪力墙结构相比,短肢剪力墙轻板结构具有良好的抗震性能,如层间侧移初始弹性刚度和水平极限承载力有所提高,而且裂缝开展缓慢均匀;轻质隔墙板可提高结构延性和房屋抗倒塌能力,同时使结构具有较大的塑性内力重分布潜力。

Experimental study on seismic behavior of short-leg shear wall system with light-weight partition board

Short-leg shear wall models on the scale of one-two were made to model the typical prototype of short-leg shear wall structure residential buildings. The short-leg shear wall models have one story and one span with light-weight partition boards or/and concrete partition boards.Models were tested to investigate the mechanical properties of short-leg shear walls with different partition boards under several loading conditions.The effect of light-weight partition on seismic behavior of short-leg shear wall was highlighted in this paper.The test results show that short-leg shear walls with light-weight partition boards or/and concrete partition boards have more horizontal ultimate bearing capability and rigidity,compared with the common short-leg shear wall.Light-weight partition board can improve the ductility,the capacity of resisting collapse and the potentials of plastic stress redistribution.
