Static Analysis of Prestressed Concrete Cantilever Bridge

Abstract:

Due to geological conditions at abutment, working mechanism and economy, a prestressed concrete bridge with double cantilevers is designed. Main dimensions and drawings are introduced and static analytical results of prestressed concrete cantilever bridge are discussed. The numerical model was built by the integrated solution system for bridge and civil Engineering-MIDAS/Civil. The main loads which affect internal force and deflection at key sections of bridge are studied, such as mid-point, support point and free end of cantilever bridge. The rules which loads affect internal forces and deflections are revealed. The results show that dead weight is an important load to control internal force and deformation of bridge with double cantilevers. The design and numerical results would give some references to the optimization of similar bridges.
