Abstract

Recent earthquakes have demonstrated the vulnerability of some bridge supports to seismic loading. Lack of confinement and poorly developed reinforcement are the main reasons for concern regarding existing bridge supports designed according to old code provisions. In this research, three dimensional as well as two dimensional finite element analyses were conducted to study the in-plane confinement stresses due to a known out-of-plane direct stress distribution. Several retrofit schemes for increasing concrete confinement stresses were modelled. The distribution of stresses and confinement pressures were evaluated for the suggested scheme by computing an in-plane stress component that corresponds to the known out-of-plane stress component, based on linear elastic theory. Stresses and deformations of a wall under combined axial and bending loads were compared with three dimensional finite element modelling.
