摘要

摘要: 对于采用透光性材料或直接曝露于室外的大跨度钢结构，在太阳辐射作用下结构温度远高于环境温度且极不均匀，可能成为结构的控制荷载，而现有规范和文献并未给出明确科学的温度作用取值依据。结合双向张弦梁实际工程，通过建立太阳辐射作用下钢结构温度场数值模拟方法，分析温度场分布规律以及结构的温度响应，给出考虑太阳辐射影响的结构温度作用的取值原则。

Abstract: For large-span steel structure with transparent materials，or the one is outdoor，its temperature is usuallynot only higher than the corresponding ambient temperature，but also very non-uniform under solar radiation．Therefore，the high non-uniform temperature is the control load for the large-span steel structures． However，there areno definite and scientific bases for determining the thermal load in current codes and published papers． Combinedwith an actual project of a bi-directional beam string structure，the numerical simulation method for the temperaturefield analysis of steel structures under solar radiation was established． The temperature distribution and the thermalload response were also analyzed．
- solar radiation /
- non-uniform temperature field /
- bi-directional beam string /
- thermal response of structure /
- temperature action value
