叠合板式剪力墙结构适用于工业化的要求,目前在建筑领域运用越来越广泛。叠合板式剪力墙的滞回性能是分析其抗震性能的重要参数,而剪力墙的非线性分析一直是研究中的热点和难点。叠合板式剪力墙与现浇整体的剪力墙在构造上存在区别:叠合板式剪力墙在现浇层和预制层之间有叠合面存在,而且底部水平接缝是通过插筋连接。通过归纳针对植筋的界面抗剪承载力计算方法,以一个已有试验作为算例,验证叠合板式剪力墙叠合面间抗剪承载力满足抗剪要求,有限元分析时可以不考虑叠合面之间的黏结滑移。依据收集到的水平接缝的抗剪承载力计算式进行计算,验证叠合板式剪力墙的底部接缝可以提供足够的抗剪承载力。在理论的基础上建立有限元模型,基于Open SEES采用不同模型对叠合板式剪力墙的滞回性能进行模拟,不同模型的模拟结果与试验结果吻合度均较好。
Laminated plate shear wall structure suitable for industrial requirements, the current use of the building more widely. The hysteretic behavior of the composite shear wall is an important parameter to analyze the seismic performance. However, the nonlinear analysis of the shear wall has been a hot and difficult issue in the research. Laminated shear wall and cast-in-place shear wall in the construction of the difference: the shear wall in the cast-in-situ layer and the prefabricated layer there is overlap, and the bottom of the horizontal seam is inserted through the tendons connection. By summarizing the calculation method of the interface shear strength for planting bars, an existing experiment is taken as an example to verify the shear resistance of the laminated surface of the composite shear wall to meet the requirements of shear resistance. The finite element analysis may not consider Slippage between laminated surfaces. Based on the formula for calculating the shear strength of the horizontal joints collected, it is verified that the bottom seam of the composite shear wall can provide enough shear capacity. Based on the theoretical foundation, the finite element model was established. Based on Open SEES, different models were used to simulate the hysteretic behavior of the composite shear wall. The simulation results of different models were in good agreement with the experimental results.
