A set of nonlinear differential and algebraic equations and boundary conditions governing the behavior of two-hinged, reinforced-concrete, circular arches under dynamic loads is formulated. These equations are first nondimensionalized and the differential equations are converted into difference equations. A numerical method is developed to solve these governing equations and predict the ultimate loads. A digital computer program for the IBM 7090 computer is prepared to handle the extensive computations involved in this method.
