Performance of reinforced concrete frames using force and displacement based seismic assessment methods

Abstract

This paper reviews the traditional force-based (FB) seismic design method and the newly proposed displacement-based (DB) seismic assessment approach. A case study is presented for reinforced concrete (RC) moment-resisting frames designed and detailed according to European and Australian earthquake code provisions, having low, medium and high ductility capacity. The aim is to assess the performance characteristics of these frames, using the well known El Centro NS earthquake ground motion as the seismic input. Overall ductility demands have been computed for the force-based analyses conducted on the typical design frames. In the second part of the paper, the performance of the case study fram..
