EARTHQUAKE RESISTANCE OF 100 MPA CONCRETE COLUMNS

This paper presents results from an extensive research program which aims to study confinement of concrete by lateral reinforcement. The current work deals with the comparison of seismic performance of ultra high strength concrete (UHSC) columns with high strength concrete (HSC) and normal strength concrete (NSC) columns. In the experimental part of the current study, column-stub specimens with concrete strengths ranging between 72 MPa and 102 MPa were tested under constant axial load and reversed cyclic displacement excursions. A performance based design procedure for confinement steel, developed based on the experimental findings, is presented here. The suggested design procedure is compared with relevant provisions of some design codes.
