The international benchmark CASH was organised by Electricité de France and the OECD Nuclear Energy Agency. The object of the benchmark was assessing the reliability of the analytical tools and prediction methodologies, as well as the engineering practice, to evaluate the strength of reinforced-concrete shear walls subjected to beyond-design earthquakes.
Principia participated in the exercise, which comprised a number of phases; in each phase, predictions made about the response were followed by dynamic tests on a shake table. The tests were designed to activate the more complex details of the dynamic response of reinforced-concrete shear walls.
