摘要
桥墩 M- φ曲线的求解一直是桥梁弹塑性阶段抗震分析的一个难点。为了解决这个问题 ,采用数值解法 ,分弹性和弹塑性两个阶段对圆柱形钢筋混凝土桥墩的 M-φ曲线进行了求解 ,并用 Vi-sual C+ + 编写了计算程序。最后应用该方法对一座桥梁实例进行了计算 ,结果表明其简便、实用。
It is always a difficult problem to solve the M φ curve of pier in elas plastic phase for bridge aseismic analysis.To solve the problem,the M φ curve of cylinder reinforcing concrete pier was calculated through numerical method in elastic and elas plastic phase.The program was developed in visual C ++ . A bridge was calculated as an example using this method.The result proved that this method was simple?practical and reliable.
