框架节点加固的抗震性能试验研究

Experimental Research on the Seismic Behavior of the Strenthening of R.C. Frame Joints

本文概述了四个十字形钢筋混凝土框架节点试件采用柱加大截面法加固后 ,在低周反复荷载作用下的试验。通过试验 ,分析了加固节点的受力机理及抗震性能 ,并提出了一些加固建议。

This paper summarizes the tests under cyclic reverse loading of four cruciform R.C.frame beam-column joints which are strengthened by enlarging column sections.Based on the test,the response of the strengthened joints and the seismic behavior are analyzed and suggestions on how to strengthen the joints are presented.
