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

<p><strong>Title</strong>: Reinforced Concrete Columns Reinforced with High-Strength Steel (NEES-2010-0904)</p> <p><b>Year Of Curation: </b>2015</p> <p><b>Description: </b>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.</p> <p><b>Award: </b>Concrete Reinforcing Steel Institute</p> <p><b>PIs & CoPIs: </b>Santiago Pujol, Andres Lepage</p> <p><b>Dates: </b>October 24, 2008 - September 20, 2010</p> <p><b>Organizations: </b>Purdue University at West Lafayette, IN, United States</p> <p><b>Facilities: </b>Purdue University at West Lafayette, IN, United States</p> <p><b>Sponsor: </b>Concrete Reinforcing Steel Institute </p> <p><b>Keywords: </b>columns, cyclic loads, high strength reinforcement, reinforced concrete</p> <p><b>Publications: </b><br /> "Cyclic Response of Concrete Columns Reinforced with High-Strength Steel"<br /> "Drift Capacity of Concrete Columns Reinforced with High-Strength Steel"</p> <nb:citations></nb:citations>
