摘要
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 momentdistribution 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.
