钢结构的有侧移和无侧移框架

摘要：刚架失稳有两种模式，分别是有侧移失稳和无侧移失稳。正确理解有侧移和无侧移失稳，是应用构件计算长度法的前提条件。目前国内对刚架失稳模式的研究比较全面，提出了多种有关刚架稳定的概念，特别是在侧移问题上。本文简单的总结了刚架稳定中侧移问题的相关概念，对有侧移和无侧移进行了比较系统的总结。全文对理解刚架失稳有很好的帮助。

abstract：frame instability has two modes, respectively, lateral instability and no lateral instability. correct understanding of lateral displacement and lateral instability, is the application of member effective length method conditions. at present domestic to frame instability mode comparison across studies, put forward a variety of relevant frame stability concept, especially in the lateral shift problems. this article briefly summarizes the stability of rigid frames in sideway questions related concepts, the lateral displacement and lateral displacement were compared systematically. the full text of the understanding of rigid frame instability have a very good help.
