Estimated Completion | Complete |
Description | The objective was to
assess the dynamic response of the operational areas (topside) of offshore structures
subject to earthquake loadings. The study consists of three parts: (1) an evaluation of the response characteristics of topside equipment under the combination of both seismic and operational loading, (2) development of approximate methods to obtain the floor response spectra based on measured seabed motions, and (3) development of a single approximate procedure for the seismic analysis of multi-degree of freedom and multiple-supported secondary systems. The project analytically simulated, the response of platforms under dynamic motion components of an earthquake. The overall direction of this work was to obtain a better understanding of the dynamic behavior of topside equipment on offshore facilities so that more accurate and safe design procedures can be formulated. |
