Wind pressure coefficients for gable roofs of intermediate slopes
… study examines the suitability of the current wind provisions of the National Building Code of Canada for design wind loads on gable roofs of intermediate roof angles (10$\sp\circ$-30$\sp\circ$). The study is initiated by the discrepancies found in recent research projects against the current …

Simulation of fluctuating wind pressures on low building roofs
Wind pressure fluctuations acting on low building roofs are important for the prediction of peak pressure values and for fatigue design purposes. Collection of several time histories of pressure fluctuations, using traditional wind tunnel measurements is time consuming and expensive. Within this …

Numerical evaluation of wind effects on buildings
The wind environment around buildings and the wind pressures on building surfaces are studied by scale-model experiments in wind tunnels and confirmed by full scale measurements. Such experiments are often expensive and time consuming. Computational wind engineering as a new branch of computational …

Ultra High Performance Fibre Reinforced Concrete Spandrel Cladding Panels in Façade Applications
… deflection of the panels under serviceability wind pressure load testing agreed well with the calculated values, in most cases deflecting less than the design limit. The failure strength of the panels was shown to be as much as four times higher than calculated. Results of the fatigue testing …

Aerodynamic stability of bridges
… the Aerodynamic Stability of Suspension Bridges. Wind has wrecked suspension bridges for over a century but the underlying cause, an increasing harmonic amplitude due to wind, has been ignored until recently. For many years bridges have been designed to withstand horizontal wind pressure, but the …

Parallel lamella dome under wind and snow loads
… the sensitivity of parallel lamella dome under wind and snow loads. The modified Riks/Wempner method is used to perform the prebuckling and postbuckling analysis. The European Convention for Constructional Steelwork (ECCS code) is used as the code of practice for design wind pressures on domes. …

Development of designer-relevant Lattice-Boltzmann Wind Field Model for urban canyons and their neighborhoods
Wind field analysis is one of the most important components for designers to achieve a thermally-comfortable and energy-efficient building design. Designers need a fast and relatively accurate wind field model to get integrated into the design workflow, but current platforms to work on are either …

Recommendations for the analysis and design of naturally ventilated buildings in urban areas
… derived in detail the physical principles of wind- and buoyancy-driven natural ventilation for a standard apartment geometry, documented and analyzed the existing data on wind pressure coefficients in terms of urban morphological parameters, and examined the ow in the urban boundary layer and …

Dynamic impact induced by tornadoes through simulations based on two-way wind-structure interactions
… This requires in-depth understanding of the wind characteristics of tornadoes and their wind effects on civil structures, based on which design tornadic wind loading can be properly determined. To achieve this, in this study, Computational Fluid Dynamics (CFD) simulations and Computational …

Cusp Ion Structures and Their Relation to Magnetopause Processes
… also limited to the cases during stable solar wind and IMF because empirical models are used to obtain the Earth's electromagnetic fields. In this dissertation, we develop a dynamic model of cusp ion structures usable for non-steady solar wind and IMF cases by using the Liouville Theorem …

A computer program for an equation of wind velocity profiles from zero to thirty feet
… of the structure and nature of natural wind and to the development of theories which can be applied to the design of buildings and other structures. Extensive studies of the velocity profile of wind have been made from the ground to the stratosphere, but investigators have concentrated …

Assessment of Analytical Procedures for Designing Metal Buildings for Wind Drift Serviceability
While designing metal buildings for wind drift, for simplicity of analysis and design, connection at base of column is considered as pinned which provides no rotational restraint. The actual behavior of the connection however, is partially rigid, that provides some rotational stiffness even in case …
