Suggested Design Guidelines for Seismic Retrofit with SIMCON and SIFCON

Abstract

This paper suggests design guidelines for seismic retrofit of nonseismically designed reinforced concrete frames using high performance fiber reinforced concretes (HPFRCs) such as slurry infiltrated mat concrete (SIMCON) and slurry infiltrated fiber concrete (SIFCON). The following retrofit schemes are addressed: column retrofit with either discontinuous or continuous SIMCON jackets and joint retrofit by either internal retrofit with prestressing bars or external SIMCON jacketing.
