Abstract

Title: An Experimental and Analytical Study of the Earthquake Response of R/C Frames with Yielding Columns (NEES-2012-1063)

Year Of Curation: 2012

Description: The structural framing systems permitted by existing design codes are in part a product of scientific scrutiny as well as a matter of subjective opinion. The use of reinforced concrete frame structures with girders flexurally stronger than the columns is avoided in seismic areas because of fear of inadequate response. The professional community, through building codes, prohibits the use of such a framing system. It is feared that when all the columns at a story yield, an elastoplastic mechanism will be formed leading to imminent. Codes also aim to prevent column strength decay under load reversals, joint failures, and shear failures of the columns. However, reinforced concrete structures exhibit post-yield stiffness under dynamic loading, rendering an elastoplastic mechanism unrealistic. This reserve stiffness may be used to limit drift to acceptable levels.
