The drive towards innovative design of structural systems assisted by more efficient materials
has resulted in ever more slender spans and lighter weight constructions. This has also been
accompanied by the growing trend of open-plan floor developments with fewer internal partitions.
As a consequence, concerns are increasingly expressed over excessive human-induced vibrations
under normal in-service conditions. These floors might be considered to fail to meet the vibration
serviceability criterion, even though in some cases they may satisfy the requirements of existing
vibration design guidelines and tolerance limits. Thus, this paper outlines a thorough back analysis
of three tested full-scale floors with respective finite element modeling to evaluate the reliability
of contemporary guidelines. It is demonstrated that current forms of design guidance may require
significant improvements in the key aspects of walking load models, response prediction and
threshold tolerance in order tomore reliably predict the actual vibration response and corresponding
vibration assessment.
