钢管混凝土组合筒体结构抗震性能试验研究
|
摘要
进行了1个钢管混凝土组合筒体结构模型的抗震性能试验。模型为比例1∶10的13层钢管混凝土组合筒体结构,外筒为钢管混凝土框支框筒结构,内筒为钢筋混凝土核心筒结构。将模型等效为两自由度体系,分别进行了地震波峰值加速度为0.22 g,0.40 g,0.62 g和1.0 g共4种工况的抗震性能动力试验。研究表明,钢管混凝土组合筒体结构是一种具有良好抗震性能的结构体系。
The seismic performance test of the model CFST tube structure has been finished.The CFST tube structure model with 13 floors and a scale of 1∶10 consists of an outer-tube and an inner-tube.The former is a framed tube supported on CFST frames and the latter is an RC tube.A series of seismic performance tests on acceleration earthquake waves in four cases(0.22 g,0.4 g,0.62 g and 1.0 g) have been fulfilled by taking the model,which is equivalent as two degrees of freedom system.The experiment has illustrated that the CFST tube structure is an outstanding structural style with excellent anti-seismic behavior.
