摘要
基于目前装配整体式混凝土剪力墙结构在工程实践中出现的诸如钢筋灌浆套筒连接质量难以控制等问题,创新性地提出模块化装配式自保温混凝土剪力墙结构体系。通过进行9片墙板平面内拟静力试验,及2根连梁拟静力试验,研究多片拼接墙板协同工作性能及装配式自保温墙板与连梁的抗震性能,验证自保温墙板及连梁正截面承载力计算公式。试验结果表明,多片拼接墙板具备良好的协同工作性能;在中等轴压比水平下,自保温墙板具备良好的抗震性能;自保温连梁正截面承载力及位移延性比均与实心连梁相近;同时提出改善高轴压比水平下自保温墙板延性的建议。相关成果可为该结构体系的工程应用提供依据。
Based on the existing problems in project practice,such as the difficulty in controlling the quality of rebar splicing by grout-filled coupling sleeve,the modular self-insulated concrete shear wall structure system was innovatively proposed.Through the pseudo-static test in-plane of 9 pieces of shear wall and the pseudo-static test of 2 coupling beams,the cooperative performance of multiple spliced shear wall and the seismic performance of assembled self-insulated shear wall and coupling beam were studied,the calculation formula of flexural capacity of self-insulated shear wall and coupling beam was verified.The test results indicated that the multiple spliced shear wall has good cooperative performance.Under the medium axial pressure ratio,the self-insulated shear wall has good seismic performance.The flexural capacity and displacement ductility ratio of the self-insulated beam are similar to the solid beam.At the same time,some suggestions on improving the ductility of self-insulated shear wall under high axial pressure ratio are put forward.The related results can provide the basis for the application of the structure system.
