不同侧移刚度下框架结构温度效应的分析研究

Analysis and research of temperature effect in the structure on the condition of different side-displacement rigidity

以有限元方法为理论基础,得出了结构梁柱内力、板中的应力大小和分布随不同侧移刚度的变化规律,根据模型有限元分析结果对板的温度应力进行了回归分析,得出了框架结构在温度工况下板最大温度应力的简化计算公式,对于在实际工程设计时考虑结构温度荷载的作用具有一定的指导意义。

The paper launchs to research on the condition of the background, distribution feature and law of beam and colurmn in the frame structure are obtained; in the end temperature stress of slab is gone on regression analysis on the basis of result of finite dement. Then simplifled compute formula of the matrix temperature stress in the slab is obtained on the condition of temperature load in the frame structure. It is valuable and helpful for the structure design on the condition of considering temperature load.
