钢管混凝土框架结构抗震性能试验研究

Experiment study on semic behaviour of concrete filled tubular frame structures

通过 2木品具有同一外形尺寸及用料的钢管混凝土框架在低周往复荷载下的试验 ,研究了该类型结构的破坏形态、变形特点、荷载 -位移滞回模型及结构耗能比 ,分析了钢管混凝土框架结构的受力特点及抗震性能 。

Through the experiment with two concrete filled steel tubular frame structures under reversed cyclic loads,which have the same shapes,materials and dimensions,several characteristics of these frame behaviours,such as failure features,deformation and energy consume ability were studied.Semic behaviours of the concrete filled steel tubular frame structures are also analysed.Experiment basis is provided for engineering design.
