设金属阻尼器的钢管混凝土柱-钢梁框架节点抗震性能

Seismic Behavior of the Connection Between Concrete Filled Steel Tubular and Steel Beam with Metal Dampers

对当前钢管混凝土框架节点研究成果进行了系统分析,指出基本型节点存在受力缺陷,很难形成强节点,而改善型节点虽然可形成强节点,但制作要求高。提出在框架体系中设置金属阻尼器,可有效实现结构的抗震性能目标。

By analyzing the research results of the concrete filled steel tubular frame connections,we know that it is difficult to form strong joint because of the defect in normal joint.Although improving typical connections can form strong joint,the criterion of making the joint is rigid.In view of the above reasons,we propose that we should set metallic dampers in the frame system,which can effectively achieve the seismic performance objectives.
