The report presents theoretical calculations of the behavior of two-hinged circular arches deflecting in their own plane and subjected to static and dynamic loads distributed uniformly over a portion of the arches. The solutions are obtained by reducing the structural description of the continuous arch to an approximate system having a finite number of degrees of freedom. The numerical results predict the behavior in and beyond the elastic range of the circular arches. The parameters describing the geometry, stiffness, and other physical characteristics of the arch were selected to represent the actual arches tested in the blast simulator at the U. S. Naval Civil Engineering Laboratory. The arches tested were fabricated from 4MI3.0 section with two strips welded to the top flanges. The radii of arches were 96.0 inches to the center lines of thin cross-sections and the central angles were about 97 degrees.The report presents theoretical calculations of the behavior of two-hinged circular arches deflecting in their own plane and subjected to static and dynamic loads distributed uniformly over a portion of the arches.
