Three-Dimensional Embedded Finite Element Model of Reinforced Concrete and Its Automatic Mesh Generation

In order to eliminate the shortcomings existing in the mesh generation of three-dimensional finite element method of reinforced concrete structures，an embedded finite element model is proposed.In this model concrete elements can be subdivided independently of the directions of reinforcement.The information of reinforcement in embedded elements can be generated automatically after the coordinates of its starting and ending points are inputted.An example shows that this model is applicable and effective.
