Wind Load Effects on Skyscrapers - Essay Example These devices are utilised in high-rise buildings reaching above 50 storeys. The TMDs enhance strength of the building while increasing comfort of residents. The Taipei 101 structure remains the building with the largest TMD weighing over six tons. This massive structure was constructed using advanced technology providing a significant breakthrough for the engineering industry. The massive structure has contributed towards the capacity for the building to withstand numerous typhoons, common in Asia. In many modern cities around the world, skyscrapers have continued to dominate the skylines. The construction of these structures continues to define the element of modernisation and evolvement of modern city designs. These magnificent structures decorating the skylines of major cities require a considerable amount of planning before commencing construction. The planning for construction of skyscrapers begins with consideration of various elements among them cost, economic efficiency and strength of the structure(Chew, 2001). The element of strength remains most important as it relates to safety of the tenants and other occupants of the building. The strength of a skyscraper remains the determinant element for the successful construction of these high rise structures. These structures remain highly susceptible to natural calamities like earth quakes and hurricanes, among others. During the planning phase for the construction of these high rise structures, those designing components seek to ensure the structure becomes sufficiently resistant to any forces that might arise. The consideration of these wind forces makes the designing phase most important. The forces exerted by winds on the structures remain fundamental for designing of high-rise structures. WIND AND TUNED MASS DAMPER Wind remains a complex phenomenon because of the variations in wind speeds resulting from interaction with the structures surrounding the wind. Wind comprises of numerous particles moving in different directions. The speed and direction of wind contributes immensely towards the effects produced by the wind(Holmes, 2007). During construction of tall structures, engineers and architects must consider the expected wind effects upon the intended structure. While normal wind force could be resisted by many structures, extreme cases like tornadoes, hurricanes present great challenges as they create massive forces, capable of collapsing entire buildings. The resulting effects of wind damage can cause massive destruction as have been recorded. Hurricanes, for example, are some of the most feared winds across the globe. Some hurricanes have enough strength to even uproot trees and destroy even the shortest of structures. During these extreme wind cases, like winds measuring 10 or higher on the Beaufort scale, the wind load affecting tall buildings is normally higher
