Abstract : An experimental study of the behavior of various structural elements subjected to repeated dynamic loadings is reported. The purpose of the inves igation was to provide experimental evidence leading to a fuller understanding of the behavior of building structures which are exposed more than once to the blast waves of a nuclear explosion. The specimens tested include pinned and fixed-base rigid frames and portal-frame knee connections. All loadings, both static and dynamic, were applied by the atomic blast simulator at the U. S. Naval Civil Engineering Laboratory. The test results are presented and a comparison is made with analytical calculations based on a simple structural theory. It was concluded from this comparison that the elementary theoretical procedures employed are adequate when applied to damage assessment studies. (Author)
