摘要
通过振动台试验研究了钢支撑-混凝土框架和防屈曲支撑-混凝土框架结构模型的动力性能.对比研究了设置这两种支撑体系的混凝土框架结构的动力特性、动力放大效果、结构损伤状态.研究表明防屈曲支撑-混凝土框架结构在罕遇地震下的抗震性能优于钢支撑-混凝土框架结构在设防地震下的抗震性能.
Shaking table tests are conducted for studying the dynamic properties of the steel-braced concrete frame and the buckling-restrained braced concrete frame. The dynamic characteristics, dynamic response amplifying effect, as well as the damage status are included in the comparison studies. It is clearly concluded that the seismic behavior of buckling-restrained braced concrete frame within the rare intensity earthquakes is better than the behavior of steel braced concrete frame within the design intensity earthquakes.
