고강도철근콘크리트 기둥의 변형능력에 관한 실험적 연구 = An Experimental Study on the Deformation of High-Strength Concrete Columns

다국어 초록 (Multilingual Abstract)

Seismic design of reinforced concrete structures if based on the ductility approach that study to improve of strength and ductility in concrete members to require.
This paper is, therefore, to study on the strength and the ductility of reinforced concrete columns subjected to high axial compression loads(0.35fc' .Ag). The test results from 1/3 scale models using high-strength reinforced concrete (fc'=560/㎠) is presented. For the research the experimental variables used the shape of shear reinforcing bar, the space of shear reinforced bar and axial force ratio.
As a result, deformation capacity of reinforced concrete columns subjected to high axial compression loads affected in the influences of axial force ratio and the space of shear reinforced bar, the shape of shear reinforcing bar.
