Analytical prediction of the flexural response of external RC joints with smooth rebars

Risultato della ricerca: Conference contribution

Abstract

An analytical model in a closed form able to reproduce the monotonic flexural response of external R.C. beamcolumn joints with smooth rebars is presented. The column is subjected to a constant vertical load and the beam to a monotonically increasing lateral force applied at the tip. The model is based on the flexural behavior of the beam and the column determined adopting a concentrated plasticity hinge model including slippage of the main bars of the beam. A simplified bilinear moment-axial force domain is assumed to derive the ultimate moment associated with the design axial force. For the joint a simple continuum model is adopted to predict shear strength and panel distortion. Experimental data given in the literature are utilized to validate the model. Finally, the proposed model can be considered a useful instrument for preliminary static verification of existing external R.C. beamcolumn joints with smooth rebars.
