Abstract:A structural investigation of a bridge pier using the finite element method is presented. For the pier, supported on three caissons with loads applied at the top, the structural action is similar to that of a deep beam. The purpose of this investiga-tion is to examine possible causes of existing cracks in the pier. The simplicity of the application and the accessibility of the computer program are emphasized. Once the finite element model is prepared, experimentation is possible with the effects of various loading conditions, all feasible support conditions and the appli-cation of external posttensioning to prevent further cracking and to relieve internal tension stresses during remedial work.
