［摘要］对2片具有不同暗柱纵筋配筋率的齿槽式连接装配式剪力墙进行拟静力加载试验，研究了暗柱配筋率对齿槽式连接装配式剪力墙压弯性能的影响。采用OpenSees建立齿槽式连接装配式剪力墙模型，进行滞回分析；采用ABAQUS建立齿槽式连接装配式剪力墙模型进行推覆分析，验证了数值模型的准确性，并对暗柱配筋率的影响做了进一步研究。研究结果表明：增大暗柱纵筋配筋率可以提高试件的耗能能力、承载能力和延性性能。［关键词］装配式剪力墙; 齿槽式连接; 暗柱配筋率; 拟静力试验; 压弯性能; 数值模拟中图分类号：TU973.16, TU317.1 文献标识码：A 文章编号：1002-848X(2016)10-0024-08
Influence of embedded-column ratio of longitudinal reinforcement on compression-bending behavior of prefabricated shear wall with tooth-grooved connectionZhang Xizhi1,2, Tian Jiesong3, Cai Weiwei 3, Chen Junjie 3, Gong Xuejian3(1 Architectural Design & Research Institute of Tianjin University, Tianjin 300072, China; 2 Civil Engineering Structure and New Materials Laboratory of Tianjin City, Tianjin University, Tianjin 300072, China; 3 School of Civil Engineering, Tianjin University, Tianjin 300072, China)Abstract: Quasi-static tests were conducted on 2 specimens of prefabricated shear wall with tooth-grooved connection with different embedded-column ratios of longitudinal reinforcement to study the influence of the ratio on compression-bending behavior of prefabricated shear wall with tooth-grooved connection. Prefabricated shear wall with tooth-grooved connection model was established for hysteresis analysis using OpenSees program. ABAQUS program was used to establish the model to conduct pushover analysis to verify the accuracy of numerical model and carry out further study on effects of embedded-column ratio of longitudinal reinforcement. The study results show that increasing the embedded-column ratio of longitudinal reinforcement can improve the energy dissipation capacity, bearing capacity and ductility performance of specimens.Keywords: prefabricated shear wall; tooth-groove connection; embedded-column ratio of longitudinal reinforcement; quasi-static test; compression-bending behavior; numerical simulation
