Simplified Models/Procedures for Estimation of Secant-to-Yielding Stiffness, Equivalent Damping, Ultimate Deformations and Shear Capacity of Bridge Piers on the Basis of Numerical Analysis
The present report gives charts and expressions for computing the equivalent stiffness and damping of bridge piers of rectangular hollow cross section at maximum displacement within the framework of displacement based design and assessment of bridges, based on the results of parametric non-linear cyclic fibre section analysis calibrated from full-scale experimental results. A state of the art review is presented concerning the different approaches that may be adopted to model shear effects in reinforced concrete columns concerning the different approaches that may be adopted to model the shear effects in reinforced concrete columns.JRC.G.5-European laboratory for structural assessmen
