DEVELOPMENT OF EARTHQUAKE-RESISTANT STEEL BAR FOR SEISMIC PERFORMANCE OF REINFORCED CONCRETE MEMBERS

Abstract

The earthquake-resistant steel bar named FLS is developed for the high performance of reinforced concrete members against the earthquake by Center for High-Tech Research Fukuyama University. The mechanical property of the steel is low yield strength and high ductility. The influence of the steel bar do to earthquake energy consumption in formation of the plastic hinge of RC members is considered. This paper describes the seismic performance of RC specimens with FLS and an application example in a seismic reinforcement.
