Numerical Analysis of Wind Loads on a Hemicylindrical Roof Building
The flow field over a three dimensional pole barn characterized by a cylindrical roof has been numerically investigated. Wind pressure and viscous loads acting on the agricultural building have been analyzed for several incoming wind directions, so as to evaluate the most critical load condition on the structure. A constant wind velocity profile, based on the maximum reference wind speed in the...
متن کاملWind Tunnel Tests for Wind Pressure Distribution on Gable Roof Buildings
Gable roof buildings are widely used in industrial buildings. Based on wind tunnel tests with rigid models, wind pressure distributions on gable roof buildings with different aspect ratios were measured simultaneously. Some characteristics of the measured wind pressure field on the surfaces of the models were analyzed, including mean wind pressure, fluctuating wind pressure, peak negative wind ...
متن کاملCoefficients and Roots of Peak Polynomials
Given a permutation π = π1π2 · · ·πn ∈ Sn, we say an index i is a peak if πi−1 < πi > πi+1. Let P (π) denote the set of peaks of π. Given any set S of positive integers, define PS(n) = {π ∈ Sn : P (π) = S}. Billey-Burdzy-Sagan showed that for all fixed subsets of positive integers S and sufficiently large n, |PS(n)| = pS(n)2 for some polynomial pS(x) depending on S. They conjectured that the co...
متن کاملNUMERICAL AND EXPERIMENTAL INVESTIGATION OF WIND PRESSURE COEFFICIENTS ON SCALLOP DOME
The wind loads considerably influence lightweight spatial structures. An example of spatial structures is scallop domes that contain various configurations and forms and the wind impact on a scallop dome is more complex due to its additional curvature. In our work, the wind pressure coefficient (Cp ) on the scallop dome surface is studied numerically and experimentally. Firstly, the programming...
متن کاملThe Impact of Variable Wind Shear Coefficients on Risk Reduction of Wind Energy Projects
Estimation of wind speed at proposed hub heights is typically achieved using a wind shear exponent or wind shear coefficient (WSC), variation in wind speed as a function of height. The WSC is subject to temporal variation at low and high frequencies, ranging from diurnal and seasonal variations to disturbance caused by weather patterns; however, in many cases, it is assumed that the WSC remains...
