The Art of Bridge Finite Element Modeling

This paper presents a three-dimensional finite element model of the bridge using MIDAS/Civil, focusing on the construction process. The model includes the main girder, arch rib, and pier as beam elements, while the suspender is represented by tensile truss elements and the arch foot concrete by solid elements.

Unit division is based on structural characteristics and precision requirements, with each bearing position featuring upper and lower double joints connected to the girder and pier, respectively, utilizing general elastic connections defined by bearing properties.

Additionally, a concrete-filled steel tube pile model is included, connected to the main beam, resulting in 769 nodes and 780 elements.
