Unified Failure Model of Reinforced Concrete Members Subjected to Hazard Loads I: Ductile Failure Analysis

A simple and unified failure model is proposed for rectangular reinforced concrete (RC) members subjected to axial loads, bending, shear force and torsion. As observed in experiments, there are two distinct types of failure mechanisms, ductile failure and brittle failure. They are analyzed separately and different analyses are proposed, respectively, only using failure criteria and equilibrium conditions. In the present paper, a lower-bound limit analysis of ductile failure is proposed. First, the warped 3-dimensional failure surface is demonstrated; then, stress distributions on the failure surface can be described; and, finally, equilibrium conditions would lead to the interaction relationship among external loads.
