RISTurbulence Modeling for Gust Loading
Publisher: American Society of Civil Engineers
Abstract: This paper presents the analytical models most in use at present for the description of the structure of turbulence in the surface atmospheric boundary layer. The study gives maximum prominence to the degree of uncertainty ...
Erratum for “New Analytical Formulation of De Marchi’s Model for a Zero-Height Side Weir” by Giovanni Michelazzo
Publisher: American Society of Civil Engineers
Alongwind Response Estimation: Structural Classification
Publisher: American Society of Civil Engineers
Abstract: The problem of dynamic alongwind response of structues to forces induced by atmospheric turbulence is treated in this paper. Starting from the classical formulation, the study suggests at first two structural standard ...
The True Linearization Coefficients for Nonlinear Systems Under Parametric White Noise Excitations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper some properties of the stochastic linearization method applied to nonlinear systems excited by parametric Gaussian white noises are discussed. In particular, it is shown that the ...
Broadband Energy Harvesting From Vibrations Using Magnetic Transduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, an adaptive electromagnetic energy harvester is proposed and analyzed. It is composed of an oscillating mass equipped with an electromagnetic transducer, whose pins are connected to a resonant resistive– ...
Equivalent Wind Spectrum Technique: Theory and Applications
Publisher: American Society of Civil Engineers
Abstract: The equivalent wind spectrum technique is a mathematical model according to which wind is schematized as a stochastic stationary Gaussian process made up of a mean‐speed profile on which an equivalent turbulent fluctuation, ...
A Numerical Study of the Possible Perturbation of Stratospheric Dynamics Due to Pinatubo Aerosols: Implications for Tracer Transport
Publisher: American Meteorological Society
Abstract: A spectral three-dimensional model of the stratosphere is used to investigate the possible dynamical effects in the stratosphere of the aerosol cloud formed after the eruption of Mt. Pinatubo. A non-negligible perturbation ...
Gust Buffeting. I: Peak Wind Velocity and Equivalent Pressure
Publisher: American Society of Civil Engineers
Abstract: Although the peak wind velocity, the equivalent pressure on rigid bodies, and the dynamic alongwind response of flexible structures are component parts of the gust buffeting problem, different procedures have been developed ...
Gust Buffeting. II: Dynamic Alongwind Response
Publisher: American Society of Civil Engineers
Abstract: The present study is the logical successor to a preceding paper, in which a procedure was developed for treating the peak wind velocity and the equivalent pressure on rigid bodies in a unified way. Based upon this formulation ...
Modeling and Simulation of an Inertia-Type Infinitely Variable Transmission
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A fully mechanical, infinitely variable transmission (IVT) based on the use of an oscillating inertia is described. The system includes a four-bar linkage mechanism, an epicyclic gear train, and ...
