Abstract

In the first place, but in no way exclusively, the paper addresses architectural
engineers facing critical design decisions in the phase of the so-called
conceptual design. The resulting design must yield a structure showing a
sound behaviour in both the serviceability limit state (SLS) and in the ultimate
limit state (ULS), also meaning that three essential criteria should be satisfied:
strength, stiffness and stability (the latter including, if relevant, an acceptable
dynamic behaviour). However, the question very often remains open as to which
of the three criteria is overruling the other ones. The paper, a synthesis of the
work of a research group headed by the author, tries to show that a conceptual
design methodology can be developed, hereby using the concept of
morphological indicators (originally developed by P. Samyn, subsequently P.
Latteur and within the research group) and a structural index (introduced by
Shanley). This methodology also gives an answer to the question which very
often arises when designing lightweight structures: design for strength or
design for stiffness? Examples in subsequent papers, presented during this
Conference and thus included in these Proceedings, illustrate the methodology,
nowadays used by our students in architectural engineering when designing and
analysing their structures.
