高強度材料を用いたRC柱部材の限界変形に関する研究

Abstract

This paper presents a limit displacement under compressive axial force of R/C columns using high strength concrete up to 160MPa and high strength steel. Based on 115 test data, equations of the limit displacement were proposed. Main factors of the equations are axial force ratio, amount of lateral reinforcement, yield strength of main bars, loading type of axial force (constant or varied) and concrete strength. The effect of buckling of the main bars and a shape of the lateral reinforcement are also included.
