Modal and pushover analysis of concrete bridges with shallow footing subjected to seismic and scour loading

General scour is the process of uniform soil erosion around pier foundations due to water flow and can reshape the dynamic behavior of bridges. In this study, the dynamic characteristics of a typical shallow foundation concrete bridge was evaluated while affected by scour. To this end, a 3D finite element model was developed capturing the nonlinear behavior of critical elements. Modal analyses were conducted to observe the changes in dominant …
