The temperature distribution of a long-span structures is not uniform due to solar radiation. Assumptions of uniform and nonuniform temperature field make the analysis results different. A mathematical model of solar radiation is established to calculate the hourly radiation intensity on the surface of a building at any geographical location. The temperature distribution of a 100m span spherical reticulated shell located in Guiyang city in China is calculated. The mechanical performance of the structure is analysed by finite element method. The following results gives: 1. the highest temperature is 48.5°C and the lowest temperature is 23.0°C. 2. The nonuniform temperature distribution makes the deformation of the reticulated shell no longer symmetrical.
