Nonlinear Finite Element Analysis of Hollow Slab Beam Bridge Reinforced with Steel Plate-Fiber Polyurethane Cement (SP-FPUC) Composite

This paper presents the nonlinear finite element analysis of hollow slab beam strengthened with steel plate-fiber polyurethane cement (SP-FPUC) composite. Comparing with single reinforcement, the innovative strengthening technique is found to improve the carrying capacity of hollow slab beam and the strain of steel bar and concrete is significantly lower under the same load. The model of a hollow slab beam bridge with damaged hinge joints on Harbin-Daqing Freeway was established to analyze the effect of composite reinforcement on the lateral transfer performance. The results indicate that the lateral distribution factors curve approaches linearity with increasing FPUC thickness and the integrity of the hollow slab beam is well improved. The stress of FPUC laminate is greatly affected by the different deflections of adjacent slabs and the stress of steel plate is related to FPUC thickness and beam deflection. This indicates that SP-FPUC has strengthening potential for deteriorated hollow slab beams.
