钢管混凝土框架结构抗震性能分析

Research on the seismic behavior of concrete-filled steel tubular frames

通过两榀具有同一外形尺寸及用料的钢管混凝土框架结构在低周往复荷载下的试验研究和理论分析,研究了该种结构的抗震性能;并与钢筋混凝土框架作了比较,得出钢管混凝土框架结构较之钢筋混凝土框架结构有抗震能力强、耗能性能好的优点,值得进一步深入研究和在工程实践中推广应用.

The seismic behavior of the concrete-filled steel tubular frame structures was analyzed by making an experiment on two concrete-filled steel tubular frame structures with the same shapes, materials and dimensions. Comparative study on the seismic behavior shows that the conerete-filled steel tubular frames have more merits than the reinforced concrete frame,which are worth studying further.
