Vibration tests of nine-story steel frame building
Nine-story steel frame building has been subjected to extensive series of forced resonance tests; seven translational and three torsional modes were investigated in detail; mode in which floor slabs vibrated horizontally as free-free beams was excited; stiffness and damping matrices were calculated from experimentally determined modal properties; damping values were found to be considerably lower than those usually mentioned in literature; damping was found to increase linearly with resonant frequencies; consistent, but small increases in damping values were found as amplitude was increased; damping mechanism is well represented by "relative" dashpots. (see also ASCE -- Proc v 92 (J Eng Mechanics Div) n EM1 Feb 1966 paper 4660 p 81-110)
