Effect of vertical distribution of mass and translational stiffness on dynamic eccentricities for a special class of multi-storey buildings
Abstract
The results from analyses which considered dynamic torsional coupling in single storey buildings have commonly been extrapolated to a special class of multi-storey buildings. Recently developed probabilistic methods are used in this paper to study the influence of various realistic vertical mass and stiffness distributions on the characteristics of torsional coupling in multi-storey buildings. Qualitative and quantitative differences between the results for single and multi-storey models are identified.
