3 hour examination	60
Coursework:   (i) Project report covering air quality from an industrial source,   (ii) Project report covering quasi-static wind loading design of a structure according to BS EN 1991-1-4.	40
Qualifying Condition(s)   An overall mark of 50% is required to pass the module.

The module provides a detailed grounding in the basics of Wind Engineering, concentrating on the three key aspects:

·         meteorology and the atmospheric boundary layer

·         wind loading theory and practice (BS EN 1991-1-4)

·         pollution dispersion theory and practice (ADMS)

Modules EMG1049 and ENG2009

To provide:

• a general understanding of the physics of atmospheric flow.

   

• a background to the general wind effects associated with buildings and terrain, including basic flow patterns and pedestrian comfort.

   

• a broad understanding of the design methods available for predicting steady and unsteady wind loads acting on a variety of buildings and structures.
• a broad understanding of the physics of dispersion in the atmosphere and awareness of the methods available for its prediction.

The objectives are that, by the end of the module, students will be able to:

• Understand, analyse and use meteorological and related data describing wind and turbulence conditions in the atmosphere near the ground.

   

• Carry out wind loading design of basic shapes of buildings and structures according to the current Codes of Practice (in particular BS EN1991-1-4) and related design guides.

   

• Recognise structural arrangements or layouts of building groups which may present problems due to wind effects and how these may be rectified.

   

• Understand the influence of buildings and structures on local wind environments.

   

• Appreciate the advantages and limitations of wind tunnel testing for obtaining wind loads on complex structures and concentration level downwind of sources.
• To understand the main issues affecting the dispersion of emissions from a wide variety of source types, conduct analyses of ground level concentrations and appreciate the level of specialist modelling required in practice (i.e. ADMS and related models).

• Basic meteorology – the development and structure of the atmospheric boundary layer.

   

• Description of flow patterns around basic structural shapes and terrain features

   

• Quasi-static design of wind loading on buildings, structures and component elements (using BS EN1991-1-4)

   

• Dynamic excitation and response of slender structures to wind loading

   

• Environmental effects of flow around buildings

   

• Wind tunnel testing and flow measurement instrumentation

   

• Dispersion in and above the atmospheric boundary layer
• Dispersion models, their strengths and weaknesses

The module is supported by printed lecture notes and a web-site.
