Abstract

The sensitivity of the response of a mass concrete dam to changes in numerical concrete cracking models is studied. In particular. the effects of varying the shapes of the fracture softening and unloading curves are examined by comparing the secondary response spectra from a series of dynamic finite element analyses of the Koyna dam. The results show that both the shape of the unloading curve and reloading curve have a strong influence on the dynamic response. It is concluded that the incorporation of crack wedging and a realistic softening model is important for this class of problem.
