Arch Dam Failure Diagnosis Applying Micro-Planes Damage Based Framework

A recently new developed set of constitutive equations which simulating the mechanical behavior of plane concrete have been implemented for monitoring the probability of cracking phenomenon within an arch concrete dam . The applied constitutive model was build on the basis of combination of micro-plane theory and damage framework. This model had been verified through comparing numerical results with experimental ones. The case study is a high elevated concrete arch concrete dam entitled Liroo dam. Obtained analysis results demonstrated that under proposed earthquake excitations, dam experiences some cracks near its middle crest. (Journal of American Science. 2010;6(12):102-107).
