| Abstract: | In this paper, a fracture model named equivalent crack fracture model(ECFM) to deal with the crack tip nonlinearity of concrete is proposed. In order to study crack extension and fracture of concrete, more specific calculation formulae of this model to the fracture tests of concrete are got, and a program DESIGN1 is developed on the basis of these formulae and numerical iteration method. ECFM and program DESIGN1,are verified by comparing measured and calculated results, and the complete process of crack extension and the fracture laws of concrete are investigated by means of ECFM and DEIGN1. |
