Behavior of a silkworm silk fiber web structure under wind load
… by silkworms and tested under an increasing wind load until failure, the deflections are recorded. To complement the experimental results, the web's structure is generated in two different models: straight fiber web and wavy fiber web models. Both models are studied under constant wind load …

Wind tunnel investigation of wind load on a ground mounted photovoltaic tracker
Wind loading is an important environmental factor to be considered in design of components and support structures of ground mounted photovoltaic tracker systems (PVT). Current understanding of action of wind on such systems is incomplete. Over the past decade, a number of investigations devoted to …

Finite Element Modelling and On-Site Measurements for Roof Mounted Photovoltaic Solar Panels under High Wind Load
The application of dynamic wind load on photovoltaic (PV) solar systems mounted on flat roofs influenced their structural behavior significantly. It is implied that when the PV solar system is exposed to extreme weather characteristics such as low temperatures, these might influence the load …

An analysis of a circular plate under tangential wind loading
… the top of a circular cylinder was placed in a wind tunnel and the pressure caused by a wind load were read over the exposed surfaces. The pressure on the plate were approximated by four terms of a Fourier cosine series. By use of the governing equation or small deflection or plates, Fourier …

An Assessment of Surface Ice Sheet Loads and Their Effects on an Offshore Wind Turbine Structure
… the effects of surface ice sheets on an offshore wind turbine. First, the main ice load cases are presented, and methods used to calculate the loads from each of these cases are explained. These load cases consist of loads from moving ice sheets, loads from non-moving ice sheets, and loads from …

Utilização de "OUTRIGGERS" em edifícios altos
… top displacement of tall buildings under lateral wind loading. A lateral load with equivalent linear distribution to the actual wind load is adopted and equations for one or several outriggers are developed seeking for optimum positioning and their efficiency in reducing sideway top displacements …

Wind effects on a hemispherical dome
A review of the past wind tunnel experiments involving the measurement of pressures over the surface of a hemispherical dome is made, and the flow parameters of these experiments are compared. A hemispherical dome is subjected to a flow in the open-throat wind tunnel at VPI&SU, and the resulting …

Reliability and effect of partially restrained wood shear walls
… partially restrained wood shear walls to resist wind and seismic loads. Wind load is the most common controlling lateral design load for these structures. In contrast, the complimenting building code, the IBC, requires either a restraining dead load or a mechanical hold down device to resist …

Wind shielding in refining and petrochemical facilities
The most influential climatic load affecting the structural design of gulf coast refining and petrochemical facilities is wind. Despite this fact, little has been done to customize wind design for these unique facilities. This paper proposes a probabilistic model to predict the magnitude of …

Wind effect on long span bridge
… types of reactions of long span bridge under wind load, such as vortex shedding, flutter and buffeting. Since all of these conditions have the chance to damage bridge structure, we calculate the particular wind speed and magnitude that will maximize the reaction. To check if the theory works …

Modeling and stability investigation of a Glulam dome
In order to predict the ultimate load capacity and failure modes of a glued-laminated timer dome, two dome models are analyzed by two finite element methods. I-DEAS is utilized to generate shell elements and to compute nodal forces for the dome model. Wind load requirements are studied, and the …
