Abstract

Wind and earthquake load have historically been conceived to act independently. However, if we reflect on the fact that major seismic events are usually followed by a number of aftershocks and that wind is constantly flowing at high intensities around wind farms, which induces additional demands of resistance to infrastructure, then the joint probability of middle-to strong earthquakes and low-to mild wind events becomes more relevant. In this paper a generalised approach is used to estimate the ratio between earthquake and wind forces and their effect on infrastructure. Following, a probabilistic analysis is carried out to show that under certain conditions the combination of these natural events can induce additional demands of strength and ductility to wind turbines which could lead to unforeseen damage.

Bibliographical note

The 2015 Paris Climate Agreement derived in escalated targets across nations to reducing CO2 emissions within the following years. In such scenario, wind energy stands as a prominent renewable source that encourages the systematic development of taller wind turbine prototypes with enhanced output generation capacity. This trend is however constrained by uncertainties about the performance of such systems when exposed to stronger wind streams, as well as by technical difficulties to build, maintain, and operate, structures exceeding 200 m in height. The paper scrutinises the feasibility of implementing hyper-tall wind energy generators by assessing their dynamic response against multi-load conditions.
