IMS with concrete filled quadrate steel tube based on finite element theory and experiments

为了研究钢管混凝土柱IMS结构的抗震性能,运用了有限元理论分析钢管混凝土柱IMS(institute fortesting of materials republic of serbia)结构抗震性能,并与抗震试验数据进行对比,检验其抗震性能。通过运用有限元软件建立2层钢管混凝土柱IMS结构模型,对所建立的结构形式进行弹性反应谱分析及弹塑性时程分析,并与振动台试验数据进行比较分析。理论分析与振动台试验均表明,该结构体系能很好地满足8度二组II类场地地区小震的作用。弹塑性时程分析及静力弹塑性分析结果表明,该体系也能很好地满足8度地区大震作用的抗震设防。钢管混凝土柱IMS的抗震性能满足要求。通过有限元理论和试验相结合的方法,得出钢管混凝土柱IMS抗震性能参数,从而为钢管混凝土IMS的设计计算和制定相关规范的提供科学的依据。

To study the capability of IMS structure with concrete filled quadrate steel tube, two storey IMS structure with concrete filled quadrate steel tube model was built. Elastic response spectrum analysis and elastic-plastic time-history analysis were used to the structure model. Compared the results of theoretical analysis with the data of the shaking table, earthquake resisting capacity of this structure was studied. This structure can be used 8.0 and 2 section and II type region of earthquake intensity category safely from the results of theoretic analysis and experiment dat. The conclusion of the study shows that the seismic behavior of ISM with concrete filled quadrate steel tube meets the requirements. The purpose of the paper is to provide some scientific dat and evidence for designing and calculating IMS with concrete filled quadrate steel tube by theoretic analysis and experiment .
