【摘要】 钢—混凝土组合结构能够充分发挥钢材和混凝土的优点,具有良好的抗震性能,越来越广泛地应用于高层建筑中。目前,应用较多的主要有钢管混凝土组合结构,为分析研究钢管混凝土组合结构的抗震性能,分别对2栋5层钢筋混凝土框架结构和钢管混凝土组合框架结构进行了地震反应弹塑性时程分析,并对多种地震波输入下的两类结构的加速度和位移反应进行了对比。理论计算分析结果表明:与钢筋混凝土结构相比,钢管混凝土结构具有较好的抗震性能。更多还原

【Abstract】 Steel and concrete composite structures combine the advantages of the two materials.With excellent seismic behavior,they are widely used in high-rise buildings.At present,concrete filled steel tubular(CFST) composite frame is one of the mostly used structure modes.To investigate its seismic behavior,time-history analysis is used in this paper to calculate earthquake response of 5-story reinforced concrete frame structures and CFST frame structures separately.Earthquake responses of the CFST and reinforced concrete are also compared in this paper.The results show that CFST frame has better seismic behavior than RC frame.更多还原
