In this paper, we analyze the load deflection behavior of the superstructure elements of beam bridges under two different beam-beam connection designs. We present a mathematical model for beam-bridge structural analysis and apply the finite element method to solve the problem. We investigate the effects of beam-beam connection design on the response and behavior of the bridge system. We also present the effect of live-loads and dead-loads on structural deformation, stress, and internal strain energy. We perform computer modeling of the beam bridge using ANSYS 19.2.
