Abstract
This manuscript presents a rigorous finite element analysis (FEA) methodology to evaluate the load-bearing capacity of simply supported steel-concrete composite bridges as of 2013. A two-stage simulation framework is detailed: first, a comprehensive literature review establishes baseline modeling practices; second, a numerical model is developed in ANSYS 15.0 to simulate static and dynamic loading scenarios. Five specific research objectives guide the study, focusing on mesh sensitivity, material nonlinearity, load distribution patterns, boundary condition effects, and model validation. Statistical analysis—via a one-table summary—compares predicted deflections and stresses against existing experimental data. Simulation results highlight the influence of mesh density and plate-girder interaction on peak stresses. Conclusions articulate key insights for bridge design codes up to 2013. Ten peer-reviewed references (all published ≤2013) support the discussion.
