Assessment of steel reinforcement ratios of concrete walls for energy dissipation categories defined by nsr-10 code

Abstract

Most structural engineers in Colombia are interested in assessing the variation of reinforcement quantities of concrete walls when designed for fulfilling requirements of categories of energy dissipation, higher than those required by nsr-10. This paper compares and discusses the steel reinforcement ratios obtained from the design of reinforced concrete walls of two housing buildings having an industrialized construction system. The two buildings have different number of stories, were designed based on different categories of seismic behavior, and are located in different seismic hazard zones. Results obtained in this study demonstrated that, for high-rise building located in intermediate seismic hazard zone and using design displacements close to the allowable drift ratio, savings in the reinforcement quantities can be obtained when structural design is carried out using requirements of des category instead of those of dmo category.
