铝合金板剪力墙抗震性能研究
|
摘要
传统钢板剪力墙的周边框架和内嵌板均采用普通钢材。随着耗能抗震理念的发展,将内嵌板中的普通钢板替换成低屈服点的铝合金板,组成铝合金板剪力墙。采用数值方法研究铝合金板剪力墙在单调荷载作用下的抗剪性能和在低周反复荷载作用下的滞回性能。研究显示:与普通钢板相比,铝合金板更易发生剪切屈曲不先于剪切屈服,对周边框架的要求更低且耗能性能更好。
In the traditional steel plate shear wall system,the conventional structural steel is selected for the boundary frame and the infill panel.Along with the development of the seismic energy dissipation concept, aluminium alloy plate shear wall is put forward,whose infill panels are replaced by aluminum alloy,with a low yield point and good ductility performance.The shear strength under monotonic loading effect and the hysteretic behavior under low cyclic loads were analysed by numerical methods for aluminum alloy plate shear wall.Studies showed that,aluminium alloy plates are more likely to happen shear buckling not prior to shear yield compared with ordinary steel plate and they have lower requirements on surrounding framework and better energy performance.
