A discussion is made regarding the application of the model of the pressures to wind load estimations for the main wind force resisting systems of circular flat roofs, using the gust effect factor approach and the LRC method.
The measured data are analyzed to obtain the information on boundary layer wind characteristics, wind pressures and wind loads on the solar collector.
Hurricane hazards, public wind pressure databases, and design wind loads are reviewed to indicate the importance of parameters other than wind speed to the building performance.
Different roof slopes and its cross-section resulted in different pressure distribution and overall wind loads on the models located in the outburst region.
Rather than using peak values, which could vary due to the stochastic nature of the data, a probabilistic analysis is performed to characterize extreme values of pressure coefficients and associated wind loads.
Current estimation of peak pressure coefficients and peak wind loads on structures in the ASCE 7 Standard [American Society of Civil Engineers, ASCE Standard, Minimum Design Loads for Buildings and Structures, ASCE 7-02, ASCE, Reston, VA, USA, 2002] is based on the assumption that they are distributed normally.
Resolution of these forces into equivalent net roof pressures reveals that wind load may be transferred from the leeward to the windward areas, leading to potential overloading of the supporting structure.
Wind tunnel experiments were carried out to measure wind loads and pressure distributions on a heliostat in stow position exposed to gusty wind conditions in a simulated part-depth atmospheric boundary layer (ABL).
This paper presents a novel conceptual design framework which takes into account the direct wind loads and pressure loads acting on a structure due to the passing of a tornado.
The system consists of individual three-tab shingles that are discretely bonded to the underlying shingles and subjected to differential out-of-plane pressures that are associated with high wind loads.
