Taiwan is located on the Pacific seismic belt, and the soil conditions of Taiwan’s offshore wind farms are softer than those in Europe. To ensure safety and stability of the offshore wind turbine supporting structures, it is important to assess the offshore wind farms seismic forces reasonably. In this paper, the relevant seismic and geological data are obtained for Chang-Bin offshore wind farm...

Abstract—One good analysis method in seismic response analysis is direct time integration, which widely adopts Rayleigh damping. An approach is presented for selection of Rayleigh damping coefficients to be used in seismic analyses to produce a response that is consistent with Modal damping response. In the presented approach, the expression of the error of peak response, acquired through compl...

The damped outrigger system is in widespread seismic area as a damping modification system. However, the relationships between exact performance and its response reduction effect has not been deeply investigated yet. This paper non-linear dynamic characteristic of single-damped systems with oil dampers or elasto-plastic considering design earthquake levels. optimal damper equations to maximize ...

This paper provides a methodology to quantify the interrelationship between the seismic intensity parameters and the structural damage. First, a computer-supported elaboration of the accelerograms provides several peak, spectral and energy seismic parameters. After that, nonlinear dynamic analyses are carried out to provide the structural response for a set of seismic excitations. Among the sev...

An experimental program was run by the Centre for Marine Science and Technology of Curtin University between March 1996 and October 1999 to study the environmental implications of offshore seismic survey noise. This work was initiated and sponsored by the Australian Petroleum Production and Exploration Association. The program: • characterised air gun signal measurements; modelled air gun array...

In this paper effect of pile-soil consideration in obtaining seismic response offshore structure is assessed due to earthquake loading. InducedSeismic force is one of the most important excitations for the dynamic response of an offshore structure. According to API, Seismic forces should be accounted in platform design for seismically active regions in order to determine the allowable seismic r...

This study investigates the mechanical behaviour of laminated elastomeric bearings with a low shape factor (LSF) and dynamic response structures mounted on them. Axial loads have significant influence LSF bearings. Most existing theories models for cannot be employed because they disregard important effects axial shortening bulging rubber layers horizontal bearing stiffness. In this study, simp...
