초록

In this paper, the extended finite element method (XFEM) is used to simulate a crack initiation and propagation and to predict post-failure behavior of reinforced concrete flexural members. The reinforced concrete beams modeled by 2-dimension plane element and 3-dimension solid element are compared with the result of RC beam experiments. The analysis results of 2D and 3D XFEM elements are similar to experimental results. It confirmed the validity of the use of the 3D XFEM model for the analysis of RC flexural members. In this process, the locking phenomenon in enriched degree of freedoms was detected. The ways to prevent the locking phenomenon are presented; reducing the time increments or the tolerance of fracture criterion. Subsequently, a reinforced concrete slab modeled by 3-dimensional XFEM was analyzed and compared with the result of a RC slab test as well as the analysis with concrete damaged plasticity (CDP) model which can represent realistic post-failure behavior of concrete. The analysis with XFEM showed a similar load capacity and crack propagation patterns. The validity of 3D XFEM to predict crack patterns and post-failure behavior of RC members was demonstrated.
