Abstract

In this paper, we propose a 3D simulation of cracks generated on concrete walls by considering multiple factors such as drying shrinkage and alkali-aggregate reaction. The proposed method divides the concrete into small voxels, and voxels are connected with springs. The simulation model is 3D-RBSM (3 Dimensional Rigid Body Spring Model) so that each voxel is not deformed. In addition, cracks grow as time passes by changing the spring strength according to the crack growth. As the result of the simulation, we have confirmed that cracks generated on the concrete wall are expanded into the inside of the concrete.
