针对叠合板式剪力墙结构,采用非线性动力推覆理论分析研究。并利用试验数据和非线性有限元软件ABAQUS对其进行低周循环往复荷载来模拟地震作用,分析研究结构的抗震性能。特别是弹塑性阶段的耗能能力,以及叠合板式剪力墙的预制板和内部现浇部分的混凝土破坏形态的探讨。比较两者在弹塑性阶段的承载力、延性以及耗能能力的大小。进一步分析叠合板式剪力墙的受力形态以及预制板和现浇部分破坏形态的差异,预测结构的抗震能力和可靠性,探索新型结构抗震性能行为,阐明结构多道抗震设防机制,解释结构破坏规律。
For the composite shear wall structure, using non-linear dynamic nappe theory analysis and research. Experimental data and nonlinear finite element software ABAQUS were used to simulate the seismic action by cyclic low-cycle cyclic loading, and the seismic performance of the structure was analyzed. Especially the energy-dissipation capacity of the elasto-plastic stage, as well as the concrete failure modes of the prefabricated slab and the in-situ cast-in-situ part of the composite shear wall. Compare their bearing capacity, ductility and energy-dissipation capacity in the elastic-plastic phase. Further analysis of the force form of the composite shear wall and the difference between the failure morphology of the precast slab and the cast-in-situ section, prediction of the seismic capacity and reliability of the structure, exploration of the seismic behavior of the new structure, clarification of the multi-channel seismic fortification mechanism, interpretation of the structure Disrupt the law.
