装配式剪力墙结构抗震试验研究
|
摘要
近年来我国各区域地震频发,房屋在地震中受损较为严重,如何提升房屋的抗震性是目前亟待解决的问题。以某市的装配式剪力墙高层住宅结构试点工程为试验对象,对其剪力墙结构进行设计改进,通过反复多次的荷载试验,分析其破坏受损过程,验证改进结构的抗震性能。试验结果表明:改进型的装配式剪力墙结构具有较好的抗震性能,应用推广前景良好。
In recent years,earthquakes have occurred frequently in various regions of China,and houses have been seriously damaged in the earthquake. How to improve the seismic resistance of houses is an urgent problem to solve. The design of the shear wall structure was improved by taking a pilot project of the high-rise residential fabricated shear wall structure in a city as the test object. Through repeated load tests,the damage process was analyzed and the improved seismic performance of the structure was verified. The test results show that the improved fabricated shear wall structure has better seismic performance and good application prospects.
