Abstract
The application of integral type non-local constitutive model to 2D RC members was investigated. The investigation is to aim at the nonlocal variable, the treatment of nonlocal variable as well as the integral region which are available to apply to the general stress field by computing the uniaxial compressive concrete member and the compression flexure failure RC beam. As the results, the nonlocal variable was suitable using the strain with the local coordinate direction to evaluate uniaxial stress. Moreover, the conventional circle integral region was not appropriate. The concept of ellipse integral region which is varied the shape and size with the state of stresses was proposed. It showed that the proposed method could evaluate the behavior of RC members approximately.
