[提要]  基于箱基设计的一些假设及其结构力学的原理，推导了核心单筒悬挂式建筑考虑核心筒P一△效应及在各种水平荷载下的侧移公式。算例表明，考虑P-△效应的核心筒侧移与箱基倾角的耦合关系是十分重要的。

Based on some hypothesis and fandamental theory of structural mechanics, the formulas calculating lateral displacemlent of core tube considering the effect of' P-△and the different type of horizontal force in the hanging structure with single core tube are deduced. The numerical example shows that it is very important to take the coupled relation into account.
