摘要

摘要: 以配箍率和水平荷载加载角度为试验参数,通过对6个钢筋混凝土箱型墩试件施加常轴力以及水平反复荷载,研究水平荷载作用方向和配箍率对钢筋混凝土箱型墩抗震性能的影响。分析各试件的滞回曲线、骨架曲线、荷载退化曲线和刚度退化曲线等方面的特征,并得出了各试件的位移延性系数和耗能系数。结果表明:钢筋混凝土箱型墩具有较好的抗震性能,水平荷载加载方向角和配箍率是影响箱型墩抗震性能的重要因素。

Abstract: Six RC box piers samples were designed and studied under the constant the axial force and reversed horizontal load.The effect of the reversed horizontal load direction and the stirrup ratio on the seismic performance of RC box pier was studied.Such seismic performance as ductility,hysteresis curve,skeleton curve,etc.of RC box piers is studied by pseudo-static test on six RC box piers.The simulation results show that RC box piers exist excellent performance of resisting seismic force,the direction of horizontal load and the stirrup ratio are the main factors affecting that performance.
