钢筋混凝土板柱结构抗倒塌性能试验研究
Experimental study on collapse performance of a RC flat plate frame structure
摘要
Abstract
A quasi-static experimental method was proposed to simulate the sudden column loss in an existing one-story 2×2 bay reinforced concrete flat plate frame structure.In the experiment,the interior column of the frame was replaced by mechanical jack to simulate its failure,2 times characteristic value of load were applied to the plate,and then unloaded the jack step by step until the vertical displacement of the interior column reached the thickness of plate.The load carrying capacity was enhanced due to the compressive membrane action.Finally,the flat plate load mechanism transfers to tension membrane action.Based on the experimental results,the failure-mechanism of structure was analyzed,the collapse-resistant of flat plate was explored and compressive membrane /tensile membrane action of flat plate was discussed.This paper exhibits an experimental method of collapse resistant performance of flat plate frame.The collapse-resistant capacity of flat plate frame constructed based on conventional design can be achieved.关键词
