摘要
通过14根型钢高强混凝土柱的低周反复加载试验,得到了型钢高强混凝土柱在压、弯、剪共同作用下的主要破坏形态,并探讨了剪跨比、配箍率、混凝土强度对型钢高强混凝土柱滞回曲线、耗能能力以及延性的影响。试验结果表明,型钢高强混凝土柱具有抵御二次地震作用的能力,其抗震性能优于钢筋混凝土柱。
Based on the experiment of 14 steel reinforced high-strength concrete columns subjected to low cyclic reversed lateral loads, the main failure patterns of steel reinforced high-strength concrete columns under combining flexure, compression and shear force are obtained, and the influence of shear span ratio, stirrup ratio and grade of concrete strength on the hysteretic curve and ductility of steel reinforced high strength concrete columns are analyzed. Test results indicate that steel reinforced high-strength concrete columns have an ability to resist one more earthquake load, the seismic performance of which is super to that of reinforced concrete columns.
