Pedestrian-Induced Load Identification from Structural,

A reliable pedestrian load model is a prerequisite for the accurate calculation of human-induced structural vibration. In recent years, many researchers have proposed pedestrian load models based on direct force measurements, such as force plates. However, direct measurement techniques often suffer from incapability when applied to real structures in operation and canUnbalanced Vibration Identification of Tangential,,Unbalanced vibration of tangential threshing cylinder increased the grain loss, shortened service life of the cylinder, and resulted in structural resonance during the rice threshing process.

Identification of Vortex-Induced Vibration of Tall,

Pinnacles on top of tall buildings are vulnerable to vortex-induced vibrations (VIVs). These structures may undergo large-amplitude vibrations that can lead to fatigue damage accumulation. To assess the performance of buildings and its appendages, numerous structural health monitoring (SHM) programs have been installed on tall buildings.

Nonlinear model parameter identification for ice-induced,

Research on ice-induced vibrations has been dominated by reduced-order models using only the first mode of the considered structure, such that its dynamics can be modeled as a single degree of freedom (DOF) oscillator. However, it was shown by M¨aatt¨ anen [6,7], that it is inadequate to consider only¨ the first mode. Principally, all modes of a structure can beIdentification of geometric parameters influencing the,,Identification of geometric parameters influencing the flow-induced vibration of a two-layer self-oscillating computational vocal fold model Brian A.
