Investigation of wind load on 1,000 m‐high super‐tall buildings based on HFFB tests

open access: yes, 2018
This paper studies the wind load on 1,000 m‐high super‐tall buildings and provides basic reference for design, including the utilization of passive and active control devices.

Individual Blade Pitch Control of Floating Offshore Wind Turbines for Load Mitigation and Power Regulation

open access: yesIEEE Transactions on Control Systems Technology, 2020
This article proposes a new strategy for individual blade pitch control to regulate power production while simultaneously alleviating structural loads on spar-type floating offshore wind turbines.

Fatigue Analysis of Greenhouse Structure under Wind Load and Self-Weight

open access: yes, 2017
The design strength of a greenhouse structure is generally determined by analyzing strength after applying wind load using the wind pressure coefficient according to a design guide.

Morphological Response of Eight Quercus Species to Simulated Wind Load

open access: yesPLoS ONE, 2016
Leaf shape, including leaf size, leaf dissection index (LDI), and venation distribution, strongly impacts leaf physiology and the forces of momentum exerted on leaves or the canopy under windy conditions.

Optimized Active Power Dispatching Strategy Considering Fatigue Load of Wind Turbines During De-Loading Operation

open access: yesIEEE Access, 2019
With the increase of wind power penetration rate in the power grid, power dispatching including wind curtailment often happens to guarantee the safety of the power system.

Mass‐loaded Winds

open access: yesThe Astrophysical Journal, 1996
This paper explores the steady state behavior of mass-loaded winds. The topology of the critical point that results from the slowing of the wind is a function of the local slope of the mass-loading function. Mass-loading functions that increase sufficiently rapidly with radius as well as gravitational force can cause the steady state approximation to ...

Large Telescope Wind Loading [PDF]

open access: yesInternational Astronomical Union Colloquium, 1984
One important large telescope design study area is the dynamic image degradation caused by wind forces upon various telescope structures and optical elements. The need to establish rapid thermal equilibration with the observatory environment further complicates the wind exposure problem.

From wind to loads: wind turbine site-specific load estimation with surrogate models trained on high-fidelity load databases

open access: yesWind Energy Science, 2018
. We define and demonstrate a procedure for quick assessment of site-specific lifetime fatigue loads using simplified load mapping functions (surrogate models), trained by means of a database with high-fidelity load simulations.
