Abstract

The continuum description of concrete fracture response is very efficient for practical applications in the safety assessment of large mass concrete structures. A porn-damage constitutive model is presented in this paper, with a direct dependence between the state of damage evolution and pore-pressure inside the fracture process zone. Experimental results published in the literature, on the water-fracture interaction effects concrete specimens, are considered to validate the numerical implementation. The proposed model may be used to analyse concrete dams, where the permeability of the intact concrete is low, and the water pressure effects are generally confined within the construction the fracture process zone of newly evolving crack profiles.
