Wave Force and Structure Response: A Comparison of Theoretical and Experimental Results Using Regular and Irregular Waves.
Abstract
An 18 foot tall jacket type structure was tested for three dimensional forces and deck deflections using regular and irregular waves of up to 2.5 feet in height. Theoretical studies for both regular and irregular wave forces are presented in conjunction with experimental results. In addition, a similar comparison for deck deflection and frequency response is presented in this report. Results indicate base shear, lift force, and overturning moment calculations using the range of hydrodynamic coefficients recommended by the American Petroleum Institute are in general agreement with experimentally determined values for wave frequencies between 0.3 and 0.8 Hz. Deck deflection measurements were significantly greater than those calculated using standard structural matrix techniques. The difference is concluded to be the result of inadequate analytical description of the test structure joints using a rigid joint analysis. (Author)
