Abstract

In this paper, the failure mechanisms of lightweight concrete beams without shear reinforcement are examined by means of nonlinear finite element analysis and experimental observations. For the 2-D computational simulations, discrete inter- and intra-element crack models using zero-thickness interface elements are used. The loss of cohesion is described in terms of a consistent damage formulation for mode I and mode II fracture. The objective is to capture the brittle failure under mixed mode fracture.
