Extensional Stiffness, of Precracked R/C Panels

Publication: Journal of Structural Engineering
Volume 111, Issue 3

Abstract

Very little experimental data is available regarding extensional stiffness in uniaxially or biaxially tensioned reinforced concrete elements. In order to improve our understanding of this important subject an experimental study was performed to determine an estimate for the effective extensional stiffness, KN, of precracked concrete panels orthogonally reinforced with No. 4 or No. 6 grade 60 reinforcing bars and subjected to uniaxial or biaxial tension. These panels are meant to be representative of a segment of a cracked containment wall subjected to internal pressurization. To obtain a relationship for the extensional stiffness, the total surface axial deformation was measured in the direction of applied tension. The tension stiffening effect of concrete was accounted for by estimating an average effective steel strain corresponding to an equivalent bond‐free reinforcing bar.
