钢筋混凝土框架结构屋盖温度效应的量测与研究

Research and Measurement of Temperature Effect on Roof of Reinforced Concrete Framed Structure

本文介绍两座钢筋混凝土屋面结构温度效应观测研究成果,分析了日照温度引起的框架结构内力分布一般规律,提出了屋面结构温度效应的计算可参照铁路桥梁设计规范方法,以及有关裂缝控制的设计建议。

The research and measured results of temperature effect from sunshine on the roofs of two reinforced conrete framed buildings are presented. The distribution pattern of the internal forces caused by sunshine temperature in the roof girders has been analyzed. The calculation method of temperature effect on roof structure in accordance with code(JBJ 2 - 85) and the design method for controlling cracks of the roofs have been proposed. The research results can be used as a reference in the design of roof structures as well for the revision of design codes.
