Dr. Kishor C. Mehta. Kishor C. Mehta is recognized worldwide as an authority on wind engineering.He is the first person from the Texas Tech University to be elected as a member of the National Academy of Engineering for his systematic studies of structural damage caused by windstorms and leadership in the development of structural design standards for wind loads.

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 civil engineering, specified loads are the best estimate of the actual loads a structure is expected to carry. These loads come in many different forms, such as people, equipment, vehicles, wind, rain, snow, earthquakes, the building materials themselves, etc. Specified loads also known as characteristic loads in many cases.
Those phone calls and the bolt substitutions convinced him to recalculate the wind loads, including the diagonal wind loads. On July 24, 1978, LeMessurier went to his office and conducted calculations on Citicorp Center's design. [21] [22] He had thought that perpendicular winds were the critical case for the building rather than quartering winds.
The characterization and formulation of dynamic load effects due to wind, waves and earthquakes on tall buildings, long-span bridges, offshore structures and other structures is carried out via fundamental analytical computational methods, and experiments at laboratory, and full-scale.
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 ...
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 ...
