深入分析梁的整体稳定

主要分析了荷载的形式和作用位置、梁的截面形式、支承条件、铺板、侧向支撑及次梁对主梁的约束程度对梁发生整体失稳的影响,并提出了提高梁整体稳定性的措施,以达到结构和构件整体稳定的目的。

The deep analysis of the whole stability of the beam

The paper mainly analyzes how the beam is affected to lose its stability by these factors,such as the forms of loading and the effect position,the cross-dimension forms,the loading conditions,the layer,the side support and the limit degree of the secondary beam on the primary beam,and points out some measures to improve the whole stability of the beam and to reach the aim of the whole stability of the structure and elements.
