Abstrakt:

Based on the new Wuhan railway station western No. 10# viaduct, a (5 × 25)m prestressed concrete continuous curved beam bridge (R=55m), this paper give a brief introduction of three models which are commonly used in bridge analysis: single beam model, shell element model and the spine-like beam model.

By thorough comparison of the accuracy, validity, dynamic performance and time-history analysis of above three models, it is demonstrated that the spine-like beam model is the most reasonable model to simulate the small radius curved bridges, with the outstanding accuracy, convenience as well as applicability.
