摘要
本文按照常规的办法,在筒中筒结构中将外框筒视为具有弯曲变形和剪切变形,同时考虑其剪切滞后影响的等代筒体,与考虑弯曲剪切变形的内筒,根据楼层相交处的变形协调条件,建立线性方程组,解出内外筒在水平荷载作用下所分配的荷载,进而可分别求出内外筒体的内力与变位.
By use of the conventional method and the compatibility condition of lateral deflections at the floor junctions, a set of equations for predicting the loads distributed on inner and outer rubes of tube -in -tube structure under lateral loading has been established, in which the outer tube is regarded as an equivalent tube considering the effects of flexural and shear deformations, as well as the effect of shear lag; but for the inner core tube, only flexural and shear edformations are taken into consideration.After the distribution of loads on inner and outer tubes have been determined, the internal forces and the deformations of both tubes can be easily compated.
