To obtain an even better match between the theoretical results and the behavior of the real bridge, more detailed modeling of the bridge is required, e.g., taking into account sliding phenomena as well as the presence of infill and spandrel walls. Also, being a 2-dimensional model, it cannot fully take into account the non-zero width of the bridge. The authors propose building a 3-dimensional finite-element model. Comparing the results from both models, the limits of our model can be investigated more thoroughly.
