Experimental Modeling of Strength and Deformation Behavior of Concrete in Direct Shear,

Abstract

Direct shear experiments on large prismatic specimens of plain concrete were conducted in a large capacity servo-controlled and structurally stiff test apparatus in order to assess the predictive capabilities of nonlinear computational analysis techniques. The objective in these experiments was not to obtain material properties but rather to investigate load-deformation response behavior and strength characteristics of a mini-structure subjected to the complex states of nonproportional loading imposed by the direct shear test. The specimens were loaded to failure under displacement control and constant normal load. The complete spectrum of structure as well as material responses were observed including prepeak elastic-hardening plastic, post-peak strength strain-softening, and localization of deformation into a shear band and continued shear gliding at a residual strength level.
