Abstract:
|
This paper is based on the experience from investigating over 400 structural collapses, incidents and serious
structural damage cases with steel structures which have occurred over the past four centuries. The cause
of the failures is most often a gross human error rather than a combination of “normal” variations in
parameters affecting the load-carrying capacity, as considered in normal design procedures and structural
reliability analyses. Human errors in execution are more prevalent as cause for the failures than errors in
the design process, and the construction phase appears particularly prone to human errors. For normal
steel structures with quasi-static (non-fatigue) loading, various structural instability phenomena have been
observed to be the main collapse mode. An important observation is that welds are not as critical a cause of
structural steel failures for statically loaded steel structures as implicitly understood in current regulations
and rules for design and execution criteria.
