Abstract：The paper calculates a equal high degree of variable cross section continuous box girder bridge with 5x60m concrete precast segment of the light rail C370 segment program in Macao. Finite element model of this bridge is created. Studies the Structural static performance of this box girder bridge,such as the structural behav?ior under normal use stage and construction condition, Structural static performance the stress state and pre-stress change of beam under different working conditions and so on. The results indicated that torsion, the beam have a good internal force performance under the ultimate load bearing capacity. Pre-stress increments have a linear change. Static increment and the loss of pre-stress value are relatively small. Edge of the beam body re?serves sufficient compressive stress, meet the security requirement.
