Phase II Tests on Shallow Unreinforced Concrete Shells
The results of tests on 17 model shells and three large shells are reported. The model shells were approximately 19 by 19 inches in plan, and the large shells were approximately 8 by 8 feet in plan. Four modes of failure were noted in the experiments: edge beam splitting, peripheral shear, transitional buckling, and mechanism development. Conditions under which the various failure modes predominate are discussed. An approximate relation for predicting the buckling load of small shells is proposed. The sagging membrane technique was found to be a simple method of casting shallow shells of small dimensions. The results of the tests indicate that shallow funicular shells constitute a structurally sound system for floors and roofs of conventional buildings and for special uses such as the decks of docks. They are expected to be particularly useful where a large load capacity is required. (Author)
