Background
A concept is defined, according to the Longman Dictionary of English
Language and Culture, as a principle or idea with a principle being defined
as a truth or belief that is accepted as a base for reasoning or action.
Structural concepts form one of the main foundations of study and design
in civil and structural engineering.
The understanding of structural concepts is a key element for students
to learn, for lecturers to teach and for engineers to use in civil and
structural engineering. The teaching and learning of structural concepts
at university needs to be enhanced to meet changes and challenges in our
learning environment and in the world of work.
In the past some of this understanding has been developed through practice
with hand calculations but now many such hand calculations are replaced
by the use puters and new methods of gaining an understanding of
structural concepts must be found. Indeed the understanding of structural
concepts, fundamental to the sound and innovative design of structures
(buildings, bridges etc) is even more important because of the wide use
puters and the, often unquestioning, reliance placed on the results
puter analyses which though correct in themselves may be based o
