Frequency Domain Method to Determine Peak Resultant Accelerations of Structure-DVA Systems

Tall, slender buildings are often susceptible to excessive wind-induced motion during common wind events, which can lead to occupant discomfort. Traditionally, the structural response is computed through modal analysis and frequency domain methods using the auto-spectra of the dynamic wind loading. The peak spatial (X-, Y-, torsion, and resultant) accelerations are often estimated using the mode shapes, peak factors, and assumed coincidence …
