BASIC STUDY ON LARGE SCALE FRACTURE SIMULATION OF RC MEMBERS USING DAMAGE MODEL BASED ON FRACTURE MECHANICS

Abstract

This paper presents a large scale fracture simulation method of RC members. In order to simulate the meso-scale fracture behavior of actual RC members, we applied the parallel processing to numerical analysis method of RC members. First, we show the formulation of the constitutive models for steel and concrete. Then, we explain the parallel processing based on domain decomposition method. The calculation efficiency of the proposed analysis method was verified. Finally, we verified the dependence of mesh size on the fracture behavior of RC beams. The numerical results demonstrated that the proposed analysis method makes possible fracture simulation of RC beams independently of mesh size.
