Abstract

This study presents the experimental study on the seismic performance of bridge column with high strength concrete and reinforcements, called New RC column. The design objective of New RC multicolumn bent is to provide same plastic moment as convention RC bridge but reducing the cross section, quantities of both longitudinal and lateral reinforcements simultaneously. Specimens RCF and NEWRCF were 4 m in center-to-center span length and 4 m in clear height. The detected compressive strength of concrete, yielding strength of longitudinal and lateral reinforcement was 80, 723, and 833 MPa for NEWRCF, respectively, while RCF were 42, 521, and 335 MPa. Experimental results demonstrated both RCF and NEWRCF satisfied the design target of moment strength, and regulations of displacement ductility in Seismic Design Specification of Highway Bridge. In addition, the pushover curves obtained by the proposed program were agreed with experimental results. Experimental results were recommended to revise the requirements of material properties of steel and lower bound of the structural ductility for multicolumn bent system.
