【摘要】 方钢管混凝土框架-RC核心筒结构因其质量轻、构件截面尺寸小、施工方便和抗侧刚度大等优点,正被越来越广泛地运用于高层建筑中。然而,目前有关其整体抗震性能的研究尚处于初步阶段,并不完善,仍缺乏一套成熟的抗震理论,为揭示其抗震特性,以一典型方钢管混凝土框架-RC核心筒结构为例,运用有限元软件对其进行多遇地震和罕地震作用下的动力时程分析,并与钢筋混凝土框架-核心筒结构进行对比,结果表明方钢管混凝土框架-RC核心筒结构不仅能够满足"小震不坏,大震不倒"的设防要求,而且其在小震和大震作用下的抗震性能均优于钢筋混凝土框架-核心筒结构。更多还原

【Abstract】 Because of concrete-filled rectangular steel tube frame-reinforced concrete core tube structure has light weight,small section size of the component,convenient construction and lateral rigidity and other advantages,it has been more and more widely used in high-rise buildings.However,it ’s the overall seismic performance research is still in the preliminary stage at present,Which is not still perfect and lack a mature seismic theory,in order to reveal the seismic characteristics,taking a typical concrete-filled rectangular steel tube frame-reinforced concrete core tube structure as an example,making dynamic time history analysis under frequent earthquake and rare earthquake through using the finite element software,and comparing with the reinforced concrete frame core tube structure.The results show that concretefilled rectangular steel tube frame-reinforced concrete core tube structure can satisfy the request of " no damage with minor earthquake and no collapsing with strong earthquake,comparing with the reinforced concrete frame core tube structure,the concrete-filled rectangular steel tube frame-reinforced concrete core tube structure has significant seismic behavior under minor earthquake and strong earthquake.更多还原
