Elsevier Dynamic Response of High-Rise Buildings to Stochastic Wind Loads

This paper presents results of a recent study addressing issues concerning the dynamic response of high-rise buildings. Utilizing a high-frequency base-balance, the alon~w;:~d, acrosswind and torsional components of aerodynamic loads and their statistical corm!ations for a wide range of generic building shapes of different aspect ratios in two approach flow conditions are quantified. A random-vibration-based procedure for estimating response of high-rise buildings is outlined. A checking procedure for building serviceability is presented for enabling designers to assess the building serviceability performance. The methodology presented here will enable designers in the preliminary design stages to assess the serviceability of buildings, the need for a detailed wind tunnel test and to evaluate the merit of design modifica-tions that may include a choice of an auxiliary damping system. 1
