Title: Reinforced Concrete Columns Reinforced with High-Strength Steel (NEES-2010-0904)

Year Of Curation: 2015

Description: In this project, the use high-strength bars (having a yield stress exceeding 80 ksi) as longitudinal reinforcement for columns is reconsidered. The focus of the work presented is on columns meeting current requirements for columns of special moment frames and columns with axial loads not exceeding the axial load at balance. The flexural strength of these columns is controlled by the strength of the steel. It follows that two sections with different grades of steel have similar moment capacities as long as the product of reinforcement ratio and yield stress is similar for both sections.
