摘要
采用DQ法分析了轴力影响不可忽略时简支梁的静力问题．在求解所导出的耦合的非线性方程组时，采用了特殊矩阵乘积技术进行解耦计算，从而使得随后的牛顿-拉弗森法迭代计算量大大减少．
This paper analyses the static problem of the simply-supported beam with DQ method in case when the axial force cannot be neglected. The matrix representation is recommended for the DQ formulation so as to make it clear and simple. The technique of special matrix products are used for decoupling calculations during the solving of the derived coupling nonlinear set of equations, thereby the workload of the iterative computations by Newton-Raphson method afterwards are greatly reduced.
