DESIGN OF GABLE ROOF BUILDING FOR WIND-IDENTIFICATION OF SENSETLVE PARAMETERS

Abstract

Windstorms are considered the most destructive natural disasters in many parts of the world. Much of the damage in these storms occurs to low rise buildings, Krishna (1995) and to large span industrial buildings, Mittal (2007). As a result, wind damage to low-rise buildings has been drawing the attention of researchers and engineers. Large suction pressure on roof and walls of buildings in a region of flow separation is a major cause of damage in windstorms. Considerable research has been performed to investigate wind load on typical low-rise gable roof buildings. Low-rise buildings are usually submerged with in atmospheric boundary layer of the earth's surface. High turbulence intensities in this regions and interferences, shelter effects are important roof loadings, with all the variations due to changes in geometry, roof angle and wind incidence angle are of paramount importance for low-rise buildings. The highest loadings on the 1 surface of a low-rise structure are generally the suctions on the roof and many structural failures are initiated there...
