Abstract

This paper presents a new hypoelasticity constitutive relationship with the material axes rotating through successive iterations. The idealization employs both fixed and rotating crack models, compressive strength degradation in the postcracking regime, and a new uniaxial stress-strain relationships for concrete under monotonically increasing loads, accounting for mesh sensitivity based on a strength formulation. This model was implemented in the nonlinear finite element analysis program "HODA". To investigate the reliability of the HODA program, results from detailed analyses of a squat shear wall tested by Cardenas, Russell and Corley (1980) including predicted load-deflection response, failure load and crack patterns at different stages of loading are presented.
