| 摘 要： | 变截面梁的控制方程为变线数微分方程 ,一般只能用各种近似方法求解 ,而且比较复杂。对于梁式构件 ,本文不求解变系数方程 ,而是用力法 ,在力法方程中 ,主、副系数和自由项的莫尔积分使用积分表 ,可以方便而且精确地求出变截面梁的弯矩和位移

| Abstract: | To avoid to solve differential equation with variable coefficient ,a simple force method combining integration table is presented in the paper for the wedge beam. In the equations of the force method, the quadratures of displacements due to unite values of the redundants and the displacements at the coordinate due to the actual loading on the released structure are used by integration table. The convenient computation and the exact result are obtained. |
