Design optimization of modular panel bridge

4.0. The modular panel bridge is a prefabricated truss bridge. Modular panel bridges have been widely adopted in civil engineering and transportation infrastructure projects worldwide due to their versatility, ease of assembly, and cost-effectiveness, which render it suitable for the construction of both permanent and temporary bridges. The research approach adopted in this project integrates both experimental and numerical analyses to comprehensively examine the structural response of the double-truss modular panel bridge. The present study utilizes the results of experimental investigations conducted by the research team of individual shear panels tested in the laboratory and a full-scale 45.7m-long double-truss modular panel bridge tested in the field. The subject bridge consists of two types of truss shear panels, namely standard shear panels (SSP) and high shear panels (HSP). Two distinctive nonlinear finite element models (FEM) are established: a simplified model, which incorporates beam-column elements; and a more rigorous model that incorporates shell elements. Both FEMs account for the material and geometrical nonlinear behaviours as well as the buckling. The performance and load-carrying capacities of the individual shear panels and full bridge are investigated, and the predictions are compared with the experimental results.
