| 摘 要： | 该文用样条有限条法导出了弯箱梁桥的应力、应变及单元刚度矩阵,推导了求一点确定内力分量的内力影响面定理,提出了等价荷载的概念,并求出了分别相应于样条结点参数及样条结点位移的等价荷载.最后编制了程序,通过静力分析和机动分析得出的影响面进行比较,说明了这种方法的正确性.

| Abstract: | The
spline finite strip method (SFSM) is used to deduce the stress,strain and unit stiffness
matrixes of the curved box bridge and testify the theorem for internal force influence
surface.The concept of equivalent load is given, and the equivalent load vectors
coordinating with spline node parameter and spline node displacement are obtained. A
program is also made to compare the internal force influence of static analysis with that
of kinematic analysis, showing the validity of the method. |
