Efficiency of lateral systems in tall steel structures

During the medieval period of the twentieth century, early structures were designed to bear only gravity loads. However, as urbanization has increased, land availability has decreased, and real estate prices have risen, there has been a growing need for vertical development to meet the various demands of human activities. To fulfill these demands, advances have been made in the development of histrength and lightweight materials, changes in structural design, and the creation of slender buildings. However, these innovative methods require careful analysis, particularly with regard to lateral load systems such as wind and earthquake loads, which are critical considerations when constructing tall buildings. A plethora of presently existing structural systems exists to undertake an analysis of the lateral resistance exhibited by tall edifices, whereby the judicious selection of the suitable structural system is indispensable to guarantee the fulfillment of all the pertaining structural and architectural parameters, while concurrently fostering sustainable development for posterity. Therefore, a proper examination of the available options is necessary to determine the most effective type of structural system that can be used to fulfill all our requirements. In this study, the response of various structural systems, such as braced frames, EBFs, etc. in a 20-story building with a typical height of 4m have been analyzed using SAP2000 software. The analysis is performed to compare various structural parameters, including Base Shear, Story Drift, Story Displacement and some frame element responses too.
