This study evaluated the lateral thermal deformation induced by environmental factors for a precast I-girder. Lateral temperature gradients across the cross-section of the girder were calculated using analytical equations based on daily solar radiation, temperature variation, and wind speed. Then the lateral thermal deformation showed an average of approximately 40% to 71% of the tolerance for the initial lateral deformation of the girder, defined in the PCI bridge design standard.
