高轴压比高强砼短柱抗震性能试验研究

Experimental study on seismic behavior of high strength concrete short-columns with high axial load ratio

为了研究高强混凝土用于大型火力发电厂主厂房框排架体系的可行性 ,通过 3根高轴压比高强混凝土短柱在反复周期荷载作用下的受力性能试验研究 ,讨论了其破坏形态及滞回特性 。

In order to work out the feasibility of high strength concrete applied to the main factory building frame and framed bent structure of large-scale thermal power stations, and based on the experimental research of 3 high-strength concrete short columns under frequency cyclic loading ,the failure shape and hysteretic characteristics were discussed, and such factors as lateral reinforcement forms and the stir up ratio which affect ductility of the components were also analyzed.
