以OpenSees为分析平台,模拟普通钢筋普通混凝土柱和高强钢筋高强混凝土柱的受力性能,进行了拟静力加载模拟,探讨了其承载力、滞回曲线、骨架曲线、以及耗能等抗震性能。研究结果表明:虽然高强钢筋高强混凝土节点的延性相对于普通钢筋普通混凝土较差,但滞回曲线形状仍较为饱满,表现出较好的耗能能力,且和普通钢筋普通混凝土柱相比承载力较高。
Taking the OpenSees as the analysis platform, the pseudo-static loading simulation of the ordinary reinforced concrete columns and the high-strength high-strength concrete columns with ordinary reinforced concrete columns was carried out. The bearing capacity, hysteresis curve, skeleton curve, energy dissipation and other seismic performance . The results show that although the ductility of high-strength high-strength concrete beam is lower than that of ordinary reinforced concrete, the shape of hysteretic curve is still relatively full, which shows better energy dissipation capacity. Compared with ordinary reinforced concrete columns, Higher.
