摘要
介绍了日照温差的特点、影响因素及计算方法,总结了近年来国内一些工程在考虑日照温差效应时的做法:包括气象参数及环境温度的取值、露天日照条件下钢构件的温度试验、考虑日照效应的荷载组合、连体钢结构合拢温度的确定、太阳照射幅度分析、温差引起的变形和内力分析、目前通用设计分析软件MIDAS/GEN、ETABS等对高层建筑结构日照温差效应分析结果的比较,以及施工阶段对日照温差效应的模拟、监测及应对措施等。
This paper contains the characteristics, influence factors, Calculation methods of effect of sunlight to high-rise structures. And also includes some project practices in recent years in China： how to make the Environment temperature, experimental study on the temperature of steel members in sunlight, load combination concerning about effect of sunlight ,how to make the folding temperature for joint structure,the analysis of radiation, analysis of deformation and stress by temperature, comparison of the analysis of MIDAS/GEN and ETABS, and simulation, monitoring, solutions for effect of sunlight in construction.
