Three-Dimensional Finite-Discrete Element Framework for the Fracturing of Reinforced Concrete Structures
Abstract:This paper presents a three-dimensional numerical model based on finite-discrete element method for simulating cracking and predicting failure in reinforced concrete (RC) structures. Discrete representation of concrete cracks is coupled with a non-linear reinforcement model where reinforcing bars interact with concrete and slip due to crack opening and steel plastic deformation. Hence, it enables a simulation of complex material behaviour of concrete and steel in cracked zones and its influence on global struc… Show more
