［摘要］對(duì)2片具有不同暗柱縱筋配筋率的齒槽式連接裝配式剪力墻進(jìn)行擬靜力加載試驗(yàn)，研究了暗柱配筋率對(duì)齒槽式連接裝配式剪力墻壓彎性能的影響。采用OpenSees建立齒槽式連接裝配式剪力墻模型，進(jìn)行滯回分析；采用ABAQUS建立齒槽式連接裝配式剪力墻模型進(jìn)行推覆分析，驗(yàn)證了數(shù)值模型的準(zhǔn)確性，并對(duì)暗柱配筋率的影響做了進(jìn)一步研究。研究結(jié)果表明：增大暗柱縱筋配筋率可以提高試件的耗能能力、承載能力和延性性能。［關(guān)鍵詞］裝配式剪力墻; 齒槽式連接; 暗柱配筋率; 擬靜力試驗(yàn); 壓彎性能; 數(shù)值模擬中圖分類號(hào)：TU973.16, TU317.1 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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
