| 摘 要： | 通过对一榀预应力装配式加固混凝土框架在低周反复荷载作用下的试验,深入研究预应力装配式加固后的钢筋混凝土框架裂缝分布、破坏形态、滞回曲线及位移延性等抗震性能。并利用SAP2000有限元分析软件对试件模型进行推覆分析。结果表明:预应力装配式加固钢筋混凝土框架具有良好的抗震性能,试验极限承载力大小和塑性铰出现位置与推覆分析结果吻合较好。

| Abstract: | It was studied that the aseismic behavior,such as crack distribution,failure mode,hysteretic curve and displacement ductility etc of a precast prestressed reinforced concrete frame through low-cyclic reversed load test.The pushover analysis of a model of the frame was done by SAP 2000 software.The result showed that such reinforced frame had good aseimic behavior;and the tested ultimate bearing capacity and the position of plastic hinge agreed well with the results of pushover analysis. |
