A buried arch bridge — Conclusions about approaches for FE modeling
Kazakov K., Mihova L., Partov D.
pages 189 - 192, full text

Conclusions are made from comparison of different finite element analyses of a buried arch bridge. The modeling is carried out by the Plaxis 2D geotechnical software. Classical and advanced constitutive models for the materials are applied. Two types of finite elements are used for modeling of the bridge structure: beam and plate elements. The soil-structure interaction is approximated by interface elements. The road traffic loading is assumed according to the model LM1 of Eurocode. Pseudo static and dynamic "time history" seismic analyses are carried out. Analysis of the ground bearing capacity is performed using the shear strength reduction technique. Mechanical behavior of the bridge is studied by analyses of states in construction and service periods.
