Dr Graham Schleyer from the University of Liverpool, School of Engineering recently delivered a short course on blast effects and analysis over two days at the Wessex Institute to a group of nine participants from Belgium, Croatia, France, Italy and the UK. This course was designed to equip engineers, security consultants and researchers with the knowledge and tools to better understand the effects on the built environment that large dynamic loads can produce from explosion sources. Practical design examples were used throughout with reference to commonly used design manuals. Hands-on sessions were included to allow delegates to solve problems using spreadsheet analysis tools. The course covered the elementary concepts of HE blast loading and response in the far-field domain, and participants were provided with an appreciation of the scope and limitations of analytical and numerical methods for modelling these types of problems. The participants especially appreciated the condensed overview of an important area to safety and security as well as the opportunity to interact and network with others on the course.
The course consisted of the following sessions:
- Introduction and general considerations
- Blast effects and characterisation
- Blast loading calculations
- Single-degree-of-freedom (SDOF) analysis methods
- Spreadsheet analysis tools
- Design of structural steel members under blast loading
- Design of RC structural members under blast loading
Dr Graham Schleyer CEng, FIMechE, SFHEA is a Senior Lecturer in the School of Engineering and a member of the Impact Research Centre at the University of Liverpool, having worked previously for several years in the gas industry and for shorter periods with leading consultancies in the UK and the US. Over the past 30 years or so he has conducted hundreds of field and laboratory tests on full-size and sub-scale structures involving gas, HE and pressurized air explosions which have provided fundamental insights into the explosion resistance of steel, RC and glazing as well as validation of numerical models and simplified analytical methods.
Dr Schleyer is co-chair of the International Conference ‘Structures Under Shock and Impact’ (SUSI) organised by the Wessex Institute. He is a previous Royal Academy of Engineering Global Research Award holder (formerly Engineering Foresight Awards), and has published widely in journals, conference proceedings, and government and industry reports.
