Seismic Analysis of Bridge Columns under Axial, Flexure, Shear, and Torsional Loadings
This study presents an inelastic non-linear three dimensional (3-D) beam element with axial, bending, shear force and torsion interaction for seismic analysis of Reinforced Concrete (RC) bridge columns. As a result of these load combinations the structural performances of RC bridge columns defer in strength, deformation capacity and failure modes. The shear mechanism along the beam is modeled by using Timoshenko beam approach with curved 3-D frame elements. The values of the concrete strength in principal directions 1, 2 and 3 are affected by the strain state in the other directions. The problem consists in solving a system of equations by combining the equilibrium conditions, compatibility conditions and constitutive laws of materials at section and structural level. The model is validated with the experimental tests subjected to real time earthquake motions.
