| 摘 要： | 本文根据超静定结构位移计算原理,运用单位虚荷载法导出了多层多跨刚架在水平荷载作用下弹性水平层间位移计算公武。该公式表明:水平层间位移仅与任意一列柱计算层以下各柱的线刚度及柱端弯矩有关,具有明显的变化规律,易于手算并适合于自编程序电算。

| Abstract: | Based on the principle of calculating elastic displacements for statically indeterminatet structures, a formula for calculating elastic displacements of multistory and multispan rigid frame under lateral loads is derived by using method of unit virtual force. This formula shows that horizontal dis-placement between two storys depends only upon relative stiffness and member-end moment of columns under this story.Using this formula, the calculetation can easily be carried out manually or on the computer. |
