What is wind loading?
The added weight of wind drifted snow. Wind erodes snow from the windward (upwind) side of obstacles, such as a ridge, and deposits the same snow on the leeward (downwind) terrain. Wind loading is a common denominator in most avalanche accidents.
How do you calculate wind loading?
Armed with pressure and drag data, you can find the wind load using the following formula: force = area x pressure x Cd. Using the example of a flat section of a structure, the area – or length x width – can be set to 1 square foot, resulting in a wind load of 1 x 25.6 x 2 = 51.2 psf for a 100-mph wind.
What is the load factor for wind load?
The formula for wind load is F = A x P x Cd x Kz x Gh, where A is the projected area, P is wind pressure, Cd is the drag coefficient, Kz is the exposure coefficient, and Gh is the gust response factor.
What is the highest wind speed recorded in UK?
Storm Eunice led to the death of 10 people across the UK and parts of western Europe including Germany and the Netherlands as wind speeds reach as high as 122 miles per hour, the fastest ever recorded in the country.
Which is code is recommended for wind load calculation?
Section 2 of this volume contains illustrative examples designed to demonstrate the various parts of the —Indian Standard I.S.: 875 (Part 3)-1987“ dealing with wind loads on buildings and structures. The examples take the reader to a point whereby the wind load on a particular structure is computed using the code.
Is wind pressure and wind load the same?
Wind load is essentially the wind pressure or wind force, in pounds per square foot, exerted on a building. There can be uplift wind load (affects roof/horizontal structures), shear wind load (horizontal pressure that can damage walls) and lateral wind load (can cause foundational issues).
What is a strong wind UK?
6. 25-31 Mph 39-49 kph 22-27 knots Strong Breeze Large tree branches move, telephone wires begin to “whistle”, umbrellas are difficult to keep under control. Larger waves form, whitecaps prevalent, spray. 7. 32-38 Mph 50-61 kph 28-33 knots Moderate or Near Gale Large trees sway, becoming difficult to walk.
Is the UK a windy country?
In terms of baseline long-term averages for ‘windiness’, the British Isles is third, behind two areas that are predominantly open seas (North Sea and Baltic Sea). Therefore it’s reasonable to draw the conclusion that the UK is one of the windiest countries in Europe.
Is standard for wind load?
NOTE: 1 – This standard IS:875 (Part 3)-1987 does not apply to buildings or structures with unconventional shapes, unusual locations, and abnormal environmental conditions that have not been covered in this Code. Special investigations are necessary in such cases to establish wind loads and their effects.
