摘　　要：为研究配有高强钢筋高强混凝土框架结构的耗能性能与抗震能力,对2层2榀1/2比例的模型结构进行了拟动力和拟静力试验,试验采用了经调幅的三种具有不同峰值加速度的地震波进行加载,共11种工况。分析了高强钢筋高强混凝土框架结构在地震作用下的滞回反应和耗能能力,探讨了结构在地震作用下的破坏机理、滞回特性及薄弱环节或部位。试验结果表明,此类结构具有较好的变形和耗能能力,抗震性能较好,所提出的方法能够用于地震区高强混凝土框架结构体系之中。This paper presents an experimental research on a high-strength concrete frame structure reinforced with high-strength stirrups. The pseudo-dynamic and pseudo-static tests were performed for an 1/2 scale frame model with two floors and two bays. The test is to develop the seismic behaviour of the frame with high-strength concrete and rebars. The specimen was subjected to 11 loading cases by using three kinds of acceleration re- cords of ground motion with the adjusted amplitude, focusing on dynamic character changes during earth- quakes, hysteretic behaviours and seismic responses. The experimental results show that this kind of frame structure can meet the requirement of the seismic performance. The results of the test may pave a new road for the application of the high strength concrete frame structure in seismic zones.
