摘要
首次将加权残数法和有限元法结合起来 ,用以分析板架结构和加劲板结构 ,其做法是对整个结构选取试函数 ,利用变分原理导出以权系数表示的梁元或板元的广义刚度矩阵和广义荷载列阵 .此方法可大大减少数值分析的计算量 。
A new method for analyzing plate frame and stiffened plate structure is presented by combining the weighted residual method with the finite element method. The sample function is chosen for the whole structure and the generalized stiffened matrix and load vector is derived by variation principle. It can decrease the calculation work and is suitable for applications in the engineering.
