FEM analysis of the strength of RC beam-to-column dowel connections under monotonic actions

摘要

One of the most common and serious damages due to an earthquake in precast buildings is the failure of the beam-to-column connection. This work investigates the shear behavior of RC beam-to-column dowel connections. A FEM model of the connection, detailed at the material level, is provided; it is validated by experimental evidences. Several parametric analyses are performed in order to investigate the influence of different variables on the connection behavior and the reliability of some literature formulae for the prediction of the dowel connection strength.
