| 摘 要： | 以2根焊接高强箍筋、高强混凝土柱试件为研究对象,进行低周反复水平荷载作用试验,研究体积配箍率的变化对柱滞回特性的影响.试验结果表明,高强混凝土柱体积配箍率较大的试件滞回曲线相对饱满,滞回环面积较大,累积滞回耗能大,吸收地震能量多,延性好.该研究结果对发展应用高强混凝土具有实际意义.

| Abstract: | In this paper, two specimens of high strength concrete columns with welding high -strength stirrups un- der low reversed cyclic horizontal loading are carried out to research the effect of the changes of the volumetric per- centage of stirrups on column hysteretic characteristics. Test results show that hysterefic curves of high strength con- crete columns volumetric percentage of stirrups larger are relatively full, the hysteretic loop area is larger, the cu- mulative hysteretie energy dissipation is larger, absorb seismic energy is bigger, and the ductility is better. The re- suits of studies on the development and application of high strength concrete are of practical significance. |
