装配式建筑剪力墙结构抗震性能分析

Seismic Performance Analysis of Prefabricated Building Shear Wall Structures

本研究旨在深入分析装配式建筑剪力墙结构的抗震性能。通过制作装配式剪力墙结构试件(VKSM)与现浇混凝土剪力墙结构试件(KSM),确保两者墙身高度、厚度、宽度均一致,以及试验的有效性。对各个试件施加强震作用,分析试件的水平位移、水平荷载,屈服荷载与位移等关键数据。同时,关注各个试件的延性系数、耗能指标的变化,得出抗震性能最佳的试件。试验结果显示,试件KSM_1的延性系数与耗能指标均低于试件VKSM_1,VKSM_2,证明装配式剪力墙结构试件的抗震性能更佳。此外,剪力墙结构的抗震性能与屈服位移、屈服荷载、延性系数、能量耗散系数等指标密切相关,抗震指标越大,剪力墙结构的抗震性能越佳。

This study aims to conduct an in-depth analysis of the seismic performance of prefabricated building shear wall structures.By making prefabricated shear wall structural specimens(VKSM)and cast-in-place concrete shear wall structural specimens(KSM),ensure that the height,thickness,and width of the two wall bodies are consistent,and the effectiveness of the test.Apply strong seismic action to each specimen,analyze key data such as horizontal displacement,horizontal load,yield load,and displacement of the specimen.At the same time,pay attention to the changes in the ductility coefficient and energy consumption index of each specimen,and determine the specimen with the best seismic performance.The test results show that the the ductility coefficient and energy consumption index of specimen KSM_1 lower than the specimen VKSM_1 and VKSM_2,with proves that the seismic performance of prefabricated shear wall structural specimens have better.In addition,the seismic performance of shear wall structures is closely related to yield displacement,yield load,ductility coefficient,energy dissipation coefficient,and other indicators,the larger the seismic index,the better the seismic performance of shear wall structures.
