Abstract |
Based on random vibration theory, a procedure for calculating the dynamic response of the tall building to time-dependent andom excitation is developed.????In this paper, the fluctuating alongwind load is assumed as time- dependent random process described by the time-independent random process??with deterministic function during a short duration of time. By deterministic function A(t) =1-exp(-t), the absolute value square of oscillatory function??is represented from author's studies.?? The time-dependent random response spectral density is represented by using the absolute value square of oscillatory function and equivalent wind load spectrum of Solari. Especially, dynamic mean square response of the tall building subected to fluctuating wind loads was derived analysis function by the??Cauchy's Integral Formula and Residue Theorem. As analysis examples, there were compared the numerical integral analytic results with the analysis function results??by??dynamic properties of the tall building. |
