Abstract

Survival of high rise buildings in large earthquakes depends directly on the ability of their framing system to dissipate energy hysteretically while undergoing large inelastic deformations. The design of steel structures for ductile response requires (a) material ductility, (b) cross section and member ductility, and (c) structural ductility. Dissipating the earthquake input energy by means of plastic excursions has to be compatible with the plastic deformation capacity of the structure. This work concerns studies on estimation of available in-elastic dissipation energy from material ductility of high tensile steels against earthquake excitations. Investigations have been carried out in respect of design philosophy, structural concepts of different grades of steel to allow for stable and reliable hysteretic energy dissipation mechanisms of high rise steel structures.
