摘要
采用大型通用有限元软件对某典型超限底部框架抗震墙-砖砌体结构运用隔震加固方法进行加固的可行性和加固效果进行了分析研究。通过对比未加固、基础隔震加固和层间隔震加固的周期、加速度、层间位移、地震剪力、隔震支座的滞回曲线及基底剪力等对加固效果进行了讨论,分析了隔震加固技术用于超限底框砌体结构加固、改善其抗震性能的可行性以及加固效果和适用情况,比较了采用基础隔震加固和层间隔震加固两种方式的优缺点,为超限底框的加固提供了一种可能解决途径。
The feasibility and effect of seismic isolation reinforcement for a typical over-limited bottom frame seismic wall-brick masonry structure are analyzed and studied by using large-scale general finite element software. By comparing the reinforcing effects of unreinforced, base isolation and story isolation, such as period, acceleration, story displacement, seismic shear, hysteretic curve of isolation bearing and base shear, the feasibility, effect and application of isolation and reinforcing technology for masonry structure with over-limit bottom frame are analyzed, and the foundation is compared. The advantages and disadvantages of isolation and story isolation reinforcement provide a possible solution for the reinforcement of over-limited bottom frames.
