A nonlinear finite element model was established using ANSYS with right material parameters for prestressed concrete box girder with steel plate and concrete composite strengthening (SPCCS). A comparison was made between analysis results and function formula data, and results show that the numerical result s of nonlinear static analysis are in good agreement with the formula results. Effect of SPCCS and steel plate strengthening was compared, and the results show that SPCCS does more effective.

This new technique has many advantages of resistance to fire, corrosion, ageing, and rapid construction speed. Test results indicated that the overall flexural behaviour of strengthened beam can be divided into three stages: precracking stage, cracking stage, and failure stage. Furthermore, a moment deflection model is developed based on the assumption of plane sections remains plane under load. The flexural behaviour of the strengthened specimens subjected to a four-point bending test was addressed by using transformed section approach. The suggested model was verified using the test data of 6 strengthened beams, and good agreement between experiment and prediction values is achieved. (2011) Trans Tech Publications, Switzerland.
