A framework for modelling the impact of extreme winds on engineering structures

Thunderstorm downbursts are relatively short-lived, extreme events which can result in wind speeds matching those of medium-strength tornadoes. In many areas of the world, downbursts are responsible for the maximum wind speed which must be considered when designing structures (the “design wind speed”). Despite this relatively little research has been undertaken on downbursts, unlike other short-duration events such as tornadoes. . This is partly due to their transient nature, low probabilities of occurrence and significant variations in structure (no two downbursts are the same). Recent work by the supervisors, based on their expertise in the physical simulation of downbursts, has led to the development of an analytical model which captures the key physical features of a downburst. In addition, work has been undertaken to develop a framework which enables this model to be easily incorporated into the design process.

In order to develop this framework further and ensure its everyday use, there are a number of outstanding issues which this proposed research seeks to address. Namely, very little is known about the downburst climatology around the world, i.e., how frequently do downbursts occur and at what locations? Can informed predictions of the effects of climate change on downburst occurrence be made? In addition, although it is acknowledged that no two downbursts are the same, common key features can be observed in all of these wind events. However, we do not yet understand the true variation of these key features and the corresponding impact they can have on structural design.

The University of Birmingham is looking to recruit a highly motivated graduate with an engineering or mathematical background. You will be working alongside a highly experienced team who are known for the quality of their research and creative approach to problem solving. Applicants are encouraged to contact Dr Mike Jesson (m.a.jesson @bham.ac.uk) and Prof Mark Sterling ([Email Address Removed]) and provide a CV before making a formal application.
