Damage Theory Based Analysis of Crack Opening Width for RC Structures

Abstract:

Starting from the damage model proposed by the design code of the RC structure, a model to evaluate the crack opening width was proposed considering the dependence between damage and crack. By implementing the proposed method into the nonlinear finite element package, the crack propagation and opening within the RC structure could be simulated in a subtle way. The agreement between the simulating results and the experimental data validates and verifies the proposed method which lays a solid foundation for the engineering analysis and design of RC structures.
