Structural behaviour due to explosions
During this course you will learn to determine the strength of structures when exposed to explosions and how to deal with the effects on the surrounding area, especially the pressure effect on neighboring buildings.
Handling the effect of an explosion in an industrial or civil environment
Explosions in a structure can cause significant damage to the structure and neighbouring buildings or equipment. In this course, you will learn, as an engineer with basic knowledge of strength theory, how to determine the strength of structures when exposed to explosion pressure waves and how to deal with various aspects surrounding the effect of an explosion on a structure.
For typical industrial gas or dust explosions, the structural response analysis is still in its early stages. To predict the structural response to explosion pressure, the design pressure is often applied as a 'safe' approach to explosion resistance. It is sometimes argued that, because an explosion is an exceptional load, there is no need to apply usual safety margins or that, due to the very fast loading, equipment tends to be stronger. These arguments are investigated thoroughly during the course.
When applying explosion venting, it is almost never checked that the external pressure does not cause damage to neighbouring equipment or buildings. As long as venting is into a safe direction and into open air, it is considered safe. Estimates of the strength of buildings when exposed to explosion pressure waves are often much too high.
Professional handling of the effect of explosions on structures
To know how to properly deal with the effect of gas and dust explosions on structures, you will learn about:
- Dynamics of structures focused on explosion response, material behaviour and consequences
- Strength calculations beyond the elastic limit, so taking into account plastic deformations
- Estimating failure limits of structures
- Cylindrical vessels: the general design formula is presented, including buckling
- Explosive effects on buildings: predicting effect with reliable empirical data
- Methods to estimate the strength of industrial buildings
- Installation of explosion venting and environmental effects (safety)
- Practical applications of the theory
Intended for
Engineers, who have a basic knowledge of structural engineering or mechanical engineering:
- Mechanical engineers involved in the structural design of process equipment
- Civil engineers who build in hazardous areas
- Explosion safety experts
Knowledge of strength calculations (stress-strain diagrams, beam calculations, frames, stress distribution over a cross-section) is required.

Frequently asked questions
In-company
Are several employees interested in the same course, do you want to enrich knowledge with the entire team or focus on your own practice? Then an in-company course could be interesting. We are happy to think along with you about the possibilities. PAOTM has extensive experience in organizing in-company courses in many technical fields for a wide range of companies. You can choose to have an existing course organized in-company for multiple employees. However, if you have a specific organizational or departmental issue, we can also design a unique course. For every customized request, we search our network at universities, knowledge institutes and the business community for the right teachers who can provide your team with the desired knowledge. We then put together a course based on your training needs, learning needs and organizational goals.
