Abstract:
Orthogonally reinforced panels, constructed of high-strength concrete, were tested under conditions of in-plane shear and normal loads. The reinforcement and loading conditions were such as to result in a concrete shear failure after yielding of the transverse reinforcement, but prior to yielding of the longitudinal reinforcement. The crack-associated damage effects observed in the compression response of the concrete, in these elements, were significant. Modifications to previously developed constitutive relations, reflecting increased deterioration in the strength and stiffness of high-strength concrete, were determined and incorporated into finite element analysis procedures. The revised constitutive models and analysis procedures were found to simulate accurately the behavior of the high-strength concrete panels.
