| 摘 要： | 本文提出了以样条能量配点法分析具有较强的横剪力作用的无柱帽楼盖的强度问题。文中以三次B样条函数作为试函数,引入Reissner薄板理论方程,以均匀配点的方式导出了适用于多种厚——跨比的无柱帽楼盖强度问题的计算格式,计算结果表明,本方法具有精度较高,程序简短,计算工作量少,计算费用低廉等许多特点。

| Abstract: | This paper presents an analysis of the strength of the floor-slab systemresting directly on columns without caps which have strong transverse shears by themethod of spline-collocation with energy principle. A general computational schemeof the strength of the floor-system has been derived for which the Reissner'stheory of thin plate is used with the cubic spline function as a trial function inthe collocation points being equally spaced. Numerical calculations show that thismethod has such merits that it is more precise, having much less computationalwork, the computer program being very short and being much lower in expenses. |
