This study utilizes an equation proposed for the calculation of the lateral-torsional buckling moment of a reinforced concrete beam to evaluate the lateral rollover stability of a precast concrete girder particularly during construction. The result of this study showed the lateral-torsional capacity of a girder significantly decreased with an increase in the initial sweep of the girder. The capacity of a girder with the initial sweep in the order of around two times the PCI tolerance becomes smaller than its ultimate flexural capacity.
