摘要
为研究抗剪连接件对内配钢板R.C.剪力墙抗震性能的影响,以9个试件在低周反复水平荷载作用下的试验结果为基础,3个有限元模型为补充,分别对试验和数值模拟结果进行对比分析,研究抗剪连接件栓钉和拉结筋对内配钢板R.C.剪力墙抗震性能的影响.研究结果表明:栓钉或拉结筋的存在可以明显提高内配钢板R.C.剪力墙的抗剪承载力和延性;同等条件下,栓钉对内配钢板R.C.剪力墙的抗剪承载力和延性的提高略优于拉结筋;随着拉结筋间距的减小,内配钢板R.C.剪力墙的承载力逐渐提高,间距达到一定程度时,提高作用趋于稳定.
In order to research the effect of shear connectors on seismic behavior of R.C. composite shear wall in-filled with steel plate, nine specimens are tested under low frequency cyclic and reversed lateral loads, and numerical analysis with 3 finite element models are conducted to supplement the tests. By the comparison of the results of tests and FEM analytical results with different parameters, It is concluded that studs and tie rods can improve the shear strength and ductility of the composition wall; with the same span of shear connector, effect of the studs on seismic behavior of R.C. composite shear wall is better than tie rods. When concrete wall and steel plate thickness meet the basic demand of details required, shear strength and ductility of shear walls are increased by decreasine the span of studs.
