Avoidance of vibration problems in mid-rise buildingsCompleted

Project leaders: Smith, Ian


There is no dispute within engineering or building regulatory circles that a proportion of
building occupants are dissatisfied with the vibration serviceability performances of
some wood multi-storey light-frame buildings in Canada and elsewhere. An open issue
is whether the problems might be exacerbated by changes in architectural styles, use of
new construction material and methods, component substitutions, increased utilization
of prefabricated wall panels, and alterations in permitted heights of wood light-frame
superstructures. Structural and building regulatory code committees have responded
with advisory notes in design codes that alert engineers and others to the possibility of
vibration serviceability problems, but such warnings are not accompanied by effective
guidance on how to design and construct buildings in ways that mitigate problems
reliably. Contemporary technical knowledge and its implementation in design only
applies to situations of limited scope where the vibration responses of floors within
buildings matches how such floors would behave if isolated from the rest of the systems
to which they belong. The project reported here explicitly recognized that wood lightframe
superstructures are complex and investigated the field performances of floors in
buildings having complexities of types commonly found in modern buildings across
