Effect of Building Characteristics on Vibration-Induced Acceleration of Non-Structural Components
The effective accelerations for non-structural components located at different heights in a building are amplified due to the vibrations of the building and the components themselves. The amplifications along the height of buildings having different heights, structural systems and stiffness were studied. Four, eight and sixteen storied, frame and frame-shear wall buildings with similar plan and storey heights, designed as per relevant Indian codes of practice, were considered in the study. The effect of the building characteristics on the amplification of motion was studied and the observed amplification was compared with the various design practices. It was observed that the design practices overestimate the floor amplification and underestimate the component amplification. However, for eight storey bare frame building, the overall amplification having the combined effect of floor amplification and component amplification was observed to be close to that specified by FEMA.
