将样条有限条法与子结构法相结合，构造成样条有限条子结构法，并将板式结构中几种放线连结方式统一表示．使之适用于各种连结条件的板式结构．通过对薄板和装配式桥梁的数值计算表明．本法可灵活处理各种边界条件、集中荷载及突变荷载情况．能大幅度降低内存．提高运算速度． The spline finite strip method is combined with the substructure method to construct the spline finite strip structure method, and the several types of wire releasing connection in the plate structure are uniformly expressed. Make it suitable for a variety of connection conditions of the plate structure. The numerical calculation of thin plates and fabricated bridges shows. This Law provides flexible handling of various boundary conditions, concentration of loads and abrupt load changes. Can significantly reduce memory. Improve computing speed.
