Title

Nonlinear Analysis of Reinforced Concrete Beam-Columns with Bond-Slip

Abstract

This paper presents a new model for nonlinear analysis of reinforced concrete beam-columns with bond-slip. The model is derived from a two-field mixed formulation with independent approximation of forces and displacements. The state determination algorithm for the implementation of the model in a general purpose nonlinear finite-element analysis program is presented and its stability characteristics are discussed. Both, bond-slip and pull-out effects, are represented in the model. The paper concludes with a correlation study to investigate the validity of the model. The study confirmed the accuracy of the model in representing global and particularly local parameters.
