摘　　要：通过对12根超高强纤维混凝土框架短柱在低周反复荷载作用下的力学性能进行试验,分析了影响纤维超高强混凝土短柱位移延性的因素,探讨了其变形与耗能能力。将试验结果与普通高强混凝土短柱试验结果相比较,结果表明在超高强混凝土短柱中掺入纤维是解决超高强混凝土短柱脆性大、延性差的一个有效的途径。The experimental research on seismic performance under axial and reversed cyclic horizontal load was carried out through 12 fiber super - high - strength concrete short frame columns. The main factors such as fiber volume content, which affect the displacement ductility of fiber super- high - strength concrete columns, were analyzed, and the deformability and energy dissipation were also discussed. Compared with the results of the normal high - strength concrete short columns, the result shows that the fiber can increase the ductility of super- high - strength columns obviously.
