高层混凝土结构短柱的抗震分析

Aseismic analysis of short concrete column in high-rise building

为了满足高层建筑延性的要求,分析了影响柱子延性的两大主要因素,介绍了如何正确判断短柱的方法,探讨了轴压比对短柱的影响,提出了提高混凝土短柱抗震性能的措施,从而提高短柱的延性,确保建筑物“中震可修,大震不倒”。

In order to meet the structural ductility requirements of high-rise building two factors influencing the ductility of column are analyzed. Method to discriminate short column is introduced. Based upon analysis of the influences of axial compression ratio on short column measures are proposed to improve seismic performances as well as ductility of short concrete column to realize ＂repairable damage under basic earthquake and no collapse under rare earthquake＂.
