中文说明：曲线梁桥结构地震反应分析的逐步微分积分方法，输出的是结构的相对于地面的位移、速度、加速度并 与状态空间法比较 。通过改变地震波的输入方向找出地震动输入主方反。采用非比例阻尼。
English Description：
Curved beam bridge gradually differentio-integral method for structural seismic response analysis, structure of output is the displacement, velocity and Acceleration relative to the ground and comparison with state space method. By altering the input seismic wave find earthquake input principal party in the opposite direction. Non-proportional damping.
