Seismic Retrofit with Discontinuous Slurry Infiltrated Mat Concrete (SIMCON) Jackets

Abstract

Older reinforced concrete structures constructed in seismically active areas of the United States are usually non-ductile and are identified as hazardous. Extensive efforts have been devoted to the development of adequate retrofitting techniques for these buildings. This paper describes a research to develop a novel seismic retrofit technique, using recently developed high performance fiber reinforced concretes (HPFRC), to solve several common problems of nonseismically designed reinforced concrete frames.
