Abstract:
This report describes the experimental and analytical results for the development of a methodology for predicting the stress-strain response of simulated concrete (mortar) in infrastructure. Lamb wave analysis is used to predict material properties of mortar specimens, which are used in the initial research as a substitute for concrete. The mortar specimens are tested to measure their stress-strain response under uni-axial compression. The results of the nondestructive and mechanical stress-strain testing are correlated to develop the model based on the Disturbed State Concept (DSC), a unified approach for modeling material behavior. This information can be used to design rehabilitation strategies, and can also lead to the development of new computer based equipment that can be used in the field for defining the remaining life. At this time, the research involved one-dimensional testing. The proposed methodology can, however, be extended and improved by conducting two- and three-dimensional testing of concrete specimens, along with laboratory and field validations.
