STUDY OF DAMAGE INDEX OF REINFORCED CONCRETE SHEAR WALL BASED ON CONSUMED ENERGY USING 3D FEM

Abstract

In this Paper, an analytical study using 3-dimensional FEM was carried out for the reinforced concrete shear wall tests under cyclic loading to estimate the damage index to the structure from the aspect of energy consumption. First, the validity of the analytical method was confirmed by the load-displacement relationship and the condition of the cracking. Next, energy division between re-bar and concrete is studied and it was suggested that there is a relation between damage of the structure and the strain energy of the concrete numerically. This damage index could be used to evaluate damage of the reinforced concrete shear wall instead of using shear strain of the wall.
