摘要
采用madis civil计算软件,对某桥双柱式钢筋混凝土柔性墩不同的加固方案模拟分析墩身最大拉压应力、自振频率、墩顶振幅、制动力位移等,最终选定最优化方案,从而达到改善柔性墩的使用性能并提高其极限承载力的目的。
This paper introduces the maximum tensile and compressive stress,natural vibration frequency,pier top amplitude and braking force displacement of pier shaft under different reinforcement schemes of double-column reinforced concrete flexible piers.The madis civil software is used to simulate and analyze different reinforcement schemes of a bridge’s double-column reinforced concrete flexible pier,and finally the optimal scheme is selected,so as to improve the service performance of the flexible pier and increase its ultimate bearing capacity.
