ANALYSIS OF PROBLEMS IN FINITE ELEMENT METHOD OF REINFORCED CONCRETE |
| |
| Abstract: | In this paper computed the nonlinear process from Load-on to failure of shallow beam and deep beams of reinforced concrete, the treatment and shearing stress release of cracked concrete element, the condition of convergence of iteration and some method of nonlinear iteration in finite element method of reinforced concrete are compared. Viewpoints are proposed in this paper. |
