Temperature Load Parameters and Thermal Effects of a Long-Span Concrete-Filled Steel Tube Arch Bridge in Tibet

Table 8

Temperature values for T₁ and T₂ in Jiacha, Tibet, for different steel pipe coating colours (°C).

Colour of steel pipe surface coating	Single pipe main arch
	Dark (e.g., red, grey)	16	10
Light (e.g., white, silver)	12	10
Temperature gradient influence range, d	D < 0.5 m: d = D/2
	D > 0.5 m: d = 0.25 m
