考虑竖向与水平接缝的工字形装配式混凝土剪力墙抗震性能试验研究
|
摘要
制作2个考虑竖向与水平接缝的工字形装配式混凝土剪力墙试件和2个对比用现浇混凝土试件,装配式试件剪力墙竖向钢筋采用金属波纹管浆锚连接技术,剪力墙翼缘全预制,腹板中部预制并在靠近翼缘300 mm范围内现浇。对其进行0.1和0.15两种轴压比条件下的低周反复荷载试验,与现浇试件比对对其抗震能力进行评价。既有试验结果表明,装配式试件能基本达到与现浇对比试件相当的抗震能力。基于试验结果,采用ABAQUS建立其有限元模型,进一步分析竖向接缝的现浇带设置对装配式剪力墙力学性能的影响及竖向接缝连接钢筋的应力情况,基于分析结果对竖向接缝现浇带及连接钢筋构造提出相关建议。
Two I-shaped precast concrete shear wall specimens with vertical and horizontal joints as well as two reference cast-in-place concrete specimens were prefabricated and tested under low-cycle reversed horizontal forces and different axial load ratios of 0.1 and 0.15. As for precast specimen, the horizontal joints were connected by rebars grouted in the metal bellows and the vertical joints were connected by part cast-in-place concrete settled at the web toe within 300 mm. The experimental results showed that precast specimens could obtain emulative aseismic performance to cast-in-place specimen. FEA models were built by ABAQUS and different detailing of part cast-in-place connections were involved. And the lateral rebars connecting precast concrete and cast-in-place concrete were analyzed in the aspect of stress. Based on the FEA results, the suggestions on the part cast-in-place connection detailing and lateral connection rebar configurations were proposed to get more efficient for practical engineering.
