Analytical Simulation of 3D Wind-Induced Vibrations of Rectangular Tall Buildings in Time Domain

The Monte Carlo simulation method for along-wind loads on tall buildings performed in the time and space domain may be only analytical viable option specific problems such as nonlinearity behavior, nonclassically damping, detailed structural models commercial software. However, both across-wind torsional-wind due to vortex shedding are not usually simulated because vertical decay constants unknown or empirical coherence functions cannot applied methods. In this paper, spectral representation (SR) is used simulate along-wind, across-wind, rectangular considering correlation between signals. Krenk root-coherence function normalized cross-spectrum direction, whereas Davenport other two types of wind loads. For loads, was assessed at frequency by changing until converge model Liang achieved. Based a three‐dimensional with translational one torsional degree freedom each floor, proposed were validated comparing elastic response approaches. Generally speaking, results show that peak displacements significantly underestimated directions when neglected. addition, advantages shown performing nonlinear history analysis bilinear isotropic material hardening directions.
