摘要
在工程上,板梁组合体系的桥梁通常比拟成板来计算。本文根据这一理论,利用样条有限条法建立了正交异性斜板条的刚度方程。用本文的方法可以计算正交构造异性斜板桥以及正交材料异性斜板桥,并能获得较高的精度。
In engineering,a composite structure of rib-plate is always calcatlated as a structural plate, from which the stiffness equation of orthotropic skew plate strip is derived by the spline finite strip method and the variation principle. By means of the stiffness equation, one can calculate both structural orthotropic skew plate bridges and natural orthotopic skew plate bridges. The precision of the calculation is high.
