Abstract

Seismic upgrade of a reinforced concrete building O. Bayrak*, B. Binici^ ^Assistant Professor, Department of Civil Engineering, University of Texas at Austin, USA Graduate Student, Department of Civil Engineering, University of Texas at Austin, USA Abstract This paper discusses results from an analytical investigation conducted to study the ductility demands imposed on reinforced concrete beams and columns of three-bay six-story reinforced concrete frames subjected to earthquake type loads. The ultimate goal of this study is to investigate and compare the behavior of Frame-NS, the ordinary moment resisting frame, and Frame-S, the special moment resisting frame designed to comply with the seismic design requirements of ACI 318-99[1], UBC-97[2], CAN A23.3-94[3] and NBC-95[4]. Determination of the critical locations in these frames and devising upgrade schemes that are consistent with the ductility demands on these locations constituted significant milestones in the seismic ret
