悬挂建筑框架结构弹性稳定性估算方法

ELASTIC STABILITY ANALYSIS FOR FRAMES IN SUSPENDED BUILDINGS

悬挂建筑框架结构是获得建筑大空间的可选方案。结构的稳定性是设计中的重要问题。本文先介绍悬挂建筑框架结构稳定性的计算模型。然后采用力矩分配法推出临界荷载的估算公式，并给出实用曲线。最后针对典型的悬持建筑结构，讨论弹性稳定性。

Suspended building structures can offer big rooms for users.In designing,the elastic stability analysis of huge frame is an important problem.This paer introduces at first a model for calculating critical loads of the frames.The formulas in two special cases are derived to estimate the critical loads with momentdistribution method,and some curves are given.Finally,the stability of two kinds of suspension structures are discussed in detail.The method proposed is useful for the design of suspended strctrtes.
