Abstract:
|
Assessment, upgrading and strengthening of ageing civil infrastructure is a major task for Europe. The aim is to extend the life-time of existing concrete bridges without loss of safety. Nonlinear finite element analysis (NLFEA) can quantify the reserve capacity of existing structures and prevent premature dismantle; however, this technique is still seldom used in practice. 2D and 3D FE models, due to high time consumption and complexity, are barely applied at large scale. In this communication, a 1D layered frame model with force-interaction is used to simulate the experimental full scale test of a RC railway bridge in Örnsköldsvik, Sweden, failing in a combination of shear-bending-torsion. Available 2D and 3D NLFEA performed with commercial software are compared. Due to the computational efficiency and relative simplicity, the 1D layered frame model can be a reference for more sophisticated continuum models in preliminary assessment stages. |
