Study On The Deflection Of Unbonded Prestressed Concrete Beam

In this paper, on the basis of analyzing methods to calculate equivalent loads in the world, a computing method of equivalent loads is presented, and prestressed concrete property and generalization prestressing force are deducted. This paper studies internal prestressed concrete deflection and analyze the effect of geometrical nolinearity on external prestressed concrete deflection.This paper shows that prestressing force effects are comprehensive, which extents the application of prestressing force technology. The effect of geometrical nolinearity is not had on internal prestressed concrete, but must been regarded on external prestressed concrete.
