Abstract

The thermodynamic analysis of long-span structure can be very complicated with the numerous members and high-degree indeterminate. In this paper, a typical spatial grid model with 4.5 x 4.5 meters plane is simulated, through the numerical simulation study on grid temperature field by solar radiation in winter and summer. The results show that: solar radiation can cause a non-uniform temperature field on grid model, of which the maximum temperature in summer is up to 52øC, temperature rising is 20øC, the maximum temperature difference among members is up to 14øC, In winter the overall temperature of the component is low; The azimuth of the chords has little effect on the temperature change law, which has great influence on the change of the web member temperature.
