Abstract: Tall building developments are rapidly increasing worldwide. In past years, developed countries have emerged as centres for brand spanking new high-rise buildings. The land is scarce and expensive, particularly in big cities like Japan, where tall buildings represent the simplest solution for solving the matter. Steel-frame structures of relatively lightweight, high strength, and high ductility became mainstream for the earthquake-resistant construction of high-rise buildings. Taller buildings also face higher wind loads hence steel is flexible, allowing the building to maneuver and deflect with the wind forces, instead of making it rigid like concrete. High-rise buildings, built completely in steel or primarily with steel are limited in India. In this paper, an attempt has been made to assess global and local ductility of a steel structure.

Keywords: High rise building, steel structure, ductility, analysis, seismic design
