Fatigue Life Assessment of Orthotropic Steel Deck with UHPC Pavement

Table 2

The transverse stress peak values of steel deck bottom side (unit: MPa).

Load cases	No pavement	Asphalt pavement	UHPC + RA05 pavement
Load Case  1
COR	109.3	17.5	−0.1
RTD	−181.5	−79.2	−36.2
Load Case  2
COR	35.1	7.9	4.9
RTD	−51.4	−30.6	−12.8

COR means at center of rib; RTD means the rib-to-deck weld.
