I am modestly proud to announce that I have achieved the ‘Certificate in Structural Behaviour’ from The Institution of Structural Engineers UK and am now eligible to utilize the GIStructE designation.
It is imperative to highlight that the examination poses a significant challenge, particularly for engineers unfamiliar with the Qualitative approach to structural analysis. I wholeheartedly endorse ‘Understanding Structural Analysis’ by David Brohn MBE PhD CEng FIStructE as the primary study material for the examination, as well as for all civil engineers seeking to deepen their understanding of the subject matter, regardless of their intent to pursue certification.

I got my certificate in structural behaviour after passing the structural behaviour exam issued by The Institution of Structural Engineers. This certificate is an internationally recognised mark of competence that proves you have the skills valued by employers: fundamental knowledge and understanding of structural behaviour, including trusses, beams, plasticity, and dynamics.
Many thanks to David Brohn MBE PhD CEng FIStructE , Mark Moppett and The Structural Exam for helping me explore the importance of this skill.

The structural behaviour course sets a very high standard as it is one of the best courses I’ve ever taken (probably my most favourite one of any course I’ve completed and also helped me pass the Certificate of Structural Behaviour Exam by IStructE).


Brilliant. Chapters are walk through lectures.

Brilliant book. I’ve attached the contents page and and example page of the book. The format is excellent; every page has 4 windows with diagrams and is accompanied with text to explain it. All ideas are walked through in a number of windows; for instance, statical indeterminacy is explained through 55 diagram windows and their accompanying text. Astonished by how easy the content is digested in this manner. Pages have an abundance of space too, which is great for jotting thoughts down in pencil. Must buy.

On a personal note, I wanted to say that I agree with you completely concerning the need for improving students and graduates understanding for the calculations they (or the software they use) produce. This is something that is perhaps even more necessary now than when your book was first published and is something I try to support in my own teaching.

Computers have changed the way structures are designed. Before computers, engineers were forced to think through the static systems, including simplifying them, so that calculations could be carried out. The engineer had so to follow the forces all the way through the structure, and with it having a detailed knowledge of the course of the forces. The use of computers has made it possible to model entire structures, have them calculated and get a lot of results that is difficult to overview and see through.

So, even if many young engineers are even extremely skilled at using calculation software, it becomes easy to put numbers in and take numbers out, whereby the static understanding of the structures actual behaviour easily disappears. Understanding how structures works is very important, not only to ensure reasonable behaviour, but also that the structures have the necessary safety. Therefore, it is important that the young engineers are provided with knowledge and intuition of the behaviour of structures, so that, for example, simply by looking at a structure, they can determine whether it is a sound structural principle. That is why courses in understanding structural behaviour are very important.

Brohn’s magnificent text presents a radical departure…Such an approach has much to recommend it

This is not your typical structures book that you read to be able design structural elements using a bunch of equations and formulas where you don’t even know where they have come from. This book instead gives you a deep understanding of structural analysis from basic principles using clear examples and diagrams, and in our time where the process of analysis and design of structures are done by computers more than ever, understanding structures and qualitative analysis is very important in order to ensure the validity of computer calculations. This book, along with Understanding Structures by Derek Seward were my bibles during my time in university while studying structural engineering, and are still the most useful of the bunch at work.

Dr Brohn is a role model, an endless source of inspiration and his book a masterpiece! I bought the book during my Masters degree and still using it all the time in the design office. A must have for students, graduates and senior engineers. Totally recommend it.

If Structural engineers would start with their detailed projects the way David Brohn describes in this book a lot of useless time from advanced modelling can be saved.

When you want to invest time in the advanced testing – then you should end up with analysing your result with the tool, David Brohn has described. If you can’t, then you really should consider to skip your advanced model and start to read “Understanding Structural Behaviour

“The President’s Award is to be presented to Dr David Brohn for his visionary approach to the education of students and graduates in structural engineering. For several decades, David’s ‘Brohn Test’ has been used by educators and employers to measure and embed an understanding of structural behaviour. David’s extraordinary efforts over a prolonged period of time have underpinned the Institution’s educational initiative in developing the Structural Behaviour Course. It is for this leadership and vision that David is to receive the President’s Award.”

– Professor Tim Ibell, President of the Institution of Structural Engineers 2015

Dr David Brohn has been awarded the President’s Award by the Institution of Structural Engineers, in recognition of his visionary approach to the education of students and graduates in structural engineering. It is only the second President’s Award ever made by the Institution. David’s ‘Brohn Test’ is used by educators and employers across the UK to measure and embed an understanding of structural behaviour in students and employees, and his extraordinary efforts have underpinned the Institution’s own new Structural Behaviour Course.

“The concept of ensuring that our graduates have a profound understanding of structural behaviour has a long and interesting history within the Institution. But in the more modern era, there is one member who stands out as a visionary. Dr David Brohn pioneered the ‘Brohn Test’, as it is affectionately known, in the early 1970s, leading the way in evidence-based tracking of the level of understanding of structural behaviour amongst graduates, ensuring that structural behaviour is learned in universities in an appropriate manner.

“His passion for the importance of this issue across the industry was far ahead of its time, and now that the Institution has its own Structural Behaviour Course firmly in place, it seems fitting that David be recognised appropriately for his pioneering work. It is with the greatest of pleasure that I have decided that Dr David Brohn should receive the President’s Award for 2015. It is a rare honour, and richly deserved.” Tim Ibell said:

Dr Brohn said: “I have been a member of the Institution for over 50 years and it has been a major part of my professional life, so I am pleased and honoured to receive this Award.”

Dr Brohn received the award at the Institution’s Annual ‘People and Paper Awards’ Luncheon held in London during June 2016.
