摘要
建筑装潢会导致结构主体隐蔽,同时也使得结构缺陷以及损伤处于隐蔽、不可见状态。为判定结构的工作状况,可采用动力特性试验的方法对结构的整体工作性能进行研究。以某钢筋混凝土框架-核心筒结构为研究对象,采用脉动法对结构进行了动力特性试验,并建立有限元模型进行计算和比较分析,对结构的工作状况作出了评价。
Building decoration can cause structure body hidden,at the same time also makes the structure defects and damage hidden and invisible. To determine the working condition of structure,the dynamic characteristics test method can be used to study the overall work performance of the structure. With a reinforced concrete frame - core tube structure as the research object,the pulsating method is adopted for structure dynamic characteristic test,and to establish the finite element model to calculate and make a comparative analysis,and the working condition of the structure is evaluated.
