摘要
Full-scale damping measurements were performed upon three classes of civil engineering structures including free-standing lattice towers, reinforced concrete buildings and pedestrian footbridges. Most of these structures were subjected to forced vibration tests to obtain structural damping estimates. Autocorrelation and random decrement procedures were used to extract total damping from load-induced resonant response signals. Both these procedures were further scrutinised in light of the measured results. A simplified analytical expression for aerodynamic damping was derived. Some damping predictors were proposed based upon the findings of this paper.
