Abstract

This paper deals with the implementation of hypo-elasticity based 3D constitutive model on Reinforced Concrete (RC) frame employing finite element technique, which uses lower order isometric solid elements HCiS18 with enhanced assumed strain (EAS) formulation to evaluate load-deformation, internal stresses produced in the elastic regime. Due attention has been paid to model concrete and the reinforcing steel with different physical and mechanical properties, which are combined together to represent its composite behaviour accurately in perfect bond situation. An in-house FORTRAN computer code has been developed for the purpose. The results of the finite element analysis are presented, compared and discussed.
