摘要
考虑剪力滞后的影响,将高层框筒结构先离散成正交各向同性板,根据最小势能原理得到各板的应力和应变表达式,再根据角柱处的位移与内力相等效的原则,将空间框筒结构等效成平面框架结构。对一个高层算例进行了计算,并与按空间框架分析的结果进行了对比。结果表明,这种简化方法具有足够的精度。
A simple method of analysis for calculating frame-tube structures is proposed. With the shear lag effects taken into account, equivalent columns are used to simplify the frame-tube to plane frame. This method is suitable for quick evaluation during the preliminary design stage. Numerical example is given to demonstrate the application and accuracy of the method.
