Rehabilitation of Concrete Dams

This webinar is the third and final course in the series on Concrete Gravity Dams.  The first webinar entitled “Introduction to Concrete Gravity Dams” (July 2012) presented information regarding the types of gravity dams, historic design and construction practices as well as lessons learned from noteworthy gravity dam failures.  The second webinar in this series entitled “Stability Evaluations for Concrete Dams” (Oct. 2013) presented information regarding potential failure modes, material properties, loading cases, federal agency criteria and stability analysis methods.*

This webinar will start with a brief recap of these first two webinars and then present successful methods for improving the structural stability of existing concrete gravity dams.  These methods can consist of either structure or foundation improvements or a combination of both.  Relevant design details in applying these methods will also be covered.  Since the majority of concrete gravity dams built in the United States pre-date modern design methods, many still require stability improvements.  This webinar is meant to help dam owners, regulators and designers better understand the options available for such improvements and best practices in applying them.
