Forced Vibration Testing of a Rehabilitated Multistory Building, Volume I
This report describes a series of steady state harmonic forced vibration tests conducted on a multistory building before and after it was rehabilitated for seismic safety. The lateral resistance added to the building significantly increased the natural frequencies of vibration. Inplane floor slab deformations were significant in both tests. The deformation was greater in the pre-rehabilitation state. The North-South and the Torsion modes both indicated inslab floor deformations. Response was measured at 5, 25 and 45 feet from the building on the surface of ground. The soil response was measurable and indicates that an analytical model of the system must be a soil/building model and interaction during an earthquake is probable.
