Hydrodynamische Belastung erdbebenerregter Offshore-Bauwerke Theoretische Analyse und experimentelle Untersuchungen. Schlussbericht

Abstract

Efficient and reliable methods have been developed for the calculation of instationary hydrodynamic loadings of earthquake-excited offshore buildings. The hybrid element method has been chosen for analysis of the interaction between structure and fluid in the frequency spectrum. Formulation of this method with extension to compressible water resulted in the program HARMAN. The program FHARMAN, in addition to HARMAN, accounts for flexible building structures. By this program not only the hydrodynamic forces but also the building responses can be calculated. Time dependency of forces, moments and pressures can be modelled by the program INSTAN. Additional experimental investigations at a test stand and with structure models were carried out to verify the theoretical methods.
