Solving Bending Problem of Reinforced Concrete Plates on Elastic Foundation of Three Parameter by Garlerkin's Method

用伽辽金法求解三参数弹性地基上受均布荷载作用的4边固定的钢筋混凝土板的弯曲问题.利用满足边界条件的试函数由板的微分方程直接获得含待定参数的待解方程,借助于迭代法解得参数值,从而获得较高精度的结果.

In this paper, the bending problem of reinforced concrete plates on elastic foundation of three parameter with four edges fixed under uniform pressure is solved by Galerkin抯 method. And by using trial function of satisfying the boundary condition and the differential equation of plates, the undetermined equation which contains undetermined parameter can be got directly, and with the help of iterative method, the parameter value is solved, thus a comparative high precision outcome will be obtained.
