Numerical Analysis of Temperature Influence on Transverse Cracks in Concrete Box-Girder Bridges

Table 1

Contrast of different thermal loads.

Type	Influencing factors	Temporality	Scope	Distribution characteristics	Effect
Sunlight temperature changes	Solar radiation	Short-term rapid change	Partial	Uneven	High local stress
Sudden drop in temperature changes	Severe cold air	Short-term changes	Total	Uniform	High stress
Annual temperature change	Slow temperature changes	Long-term and slow	Total	More uniform	Large overall displacement
