Abstract
The key to analyze the temperature effect and dcrtermine the construction closure temperature of steel structures is the determinaion of the distribution of temperature field. Temperature distribution of steel members is non uniform and complicated under the action of sunlight and difficult to determine. Is this paper, based on ASHRAE clear sky model, APDL language was adopted in software ANSYS to conduct numerical simulation of the temperature of box steel members during the daytime of summer solstice. The effects of factors such as solar radiation intensity, convective heat transfer coefficient and surface solar radiation absorption coefficient on the temperature field of steel components were analyzed. The results show that the highest temperature of steel members is 78. 411℃ in summer solstice and the maximum temperature increase is 44.803℃, under the action of sunlight, solar radiation intensity, convective heat transfer coefficient and surface solar radiation absorption coefficient play a leading role in affecting the temperatures of steel members.关键词
