Timber floors are particularly susceptible to noise and vibration issues when compared to other construction methods, such as concrete floors. This is due to the relatively high stiffness-to-mass-density-ratio of timber floors, which enables so-called ‘lightweight’ floor constructions, in contrast t ...

Buildings and other civil structures can be “interrogated” through their vibration signatures: because natural frequencies, mode shapes and damping depend on mass, stiffness and energy-dissipation mechanisms, measuring ambient or forced responses reveals those properties without destructive tests.

It is well acknowledged that as the height of a building increases, wind forces tend to become the controlling design loads. In tall, slender and flexible structures, wind-induced vibration serviceability is more critical than in low-rise buildings, where strength is usually the governing design cri ...
