Flow visualization of wind speed contours around a house Wind engineering covers the aerodynamic effects of buildings Damaged wind turbines due to hurricane Maria. Wind engineering is a subset of mechanical engineering, structural engineering, meteorology, and applied physics that analyzes the effects of wind in the natural and the built environment and studies the possible damage ...
ASCE Journals first appeared online in the Fall of 2000. The online collection was designated ASCE Research Library in the Fall of 2004 with the addition of ASCE Proceedings papers. In June 2012, the platform migrated from Scitation, to Literatum managed by Atypon and the site was renamed ASCE Library. In June 2013, e-books and standards were ...
In the United States, the wind speed used in design is often referred to as a "3-second gust", which is the highest sustained gust over a 3-second period having a probability of being exceeded per year of 1 in 50 (ASCE 7-05, updated to ASCE 7-16). [18] This design wind speed is accepted by most building codes in the United States and often ...
When estimating wind loads on structures the terrains may be described as suburban or dense urban, for which the ranges are typically 0.1-0.5 m and 1-5 m respectively. [ 2 ] In order to estimate the mean wind speed at one height ( z 2 {\displaystyle {{z}_{2}}} ) based on that at another ( z 1 {\displaystyle {{z}_{1}}} ), the formula would be ...
The IEEE 693: Recommended Practice for Seismic Design of Substations. [1] is a Institute of Electrical and Electronics Engineers standard.This standard is recognized also by American National Standards Institute, and is used mainly in the American Continent.
Dead loads have small load factors, such as 1.2, because weight is mostly known and accounted for, such as structural members, architectural elements and finishes, large pieces of mechanical, electrical and plumbing (MEP) equipment, and for buildings, it's common to include a Super Imposed Dead Load (SIDL) of around 5 pounds per square foot ...
He found that, for four of the eight tiers of chevrons, quartering winds would create a 40 percent increase in wind loads and a 160 percent increase in the load at the bolted joints. [17] Citicorp Center's use of bolted joints and the loads from quartering winds would not have caused concern if these issues had been isolated.
