- Abstract
- The punching shear resistance of lightweight concrete offshore structures for the Arctic is being investigated at the National Bureau of Standards on behalf of The Minerals Management Service of the U.S. Department of the Interior in cooperation with the following U.S. oil companies: Chevron Corporation, Exxon Production Research Company, Mobile Research and Development Corporation, and Sohio Petroleum Company. This report presents results of a 1/25-scale model study investigating the punching shear behavior of both plate and shell specimens. The study was undertaken to provide guidance for the selection of parameters for use in a larger, 1/6-scale, testing program. Initial tests on 1/6-scale plate specimens resulted in a complex combined punching and beam shear failure. The 1/25-scale models were capable of qualitatively replicating the failure mechanism that occurred in the initial 1/6-scale plate tests, and parameters were adjusted in the 1/25-scale specimens until a primarily punching shear failure was obtained in these specimens. Some quantitative agreement was also observed between the 1/25-scale and 1/6-scale tests. Recommendations are made for the 1/6-scale testing program.
