【Abstract】 In this paper, solid element of the finite element program is used to analyze the box girder stress of a partial prestressed-concrete cable-stayed bridge .The transverse stress of the box girder with prestress in three directions is grasped. Furthermore the negative shear lag is found. The analysis also has the reference value for the similar engineering.更多还原
