콘크리트 충전 원형강관 기둥-H형강 보 접합부의 구조적 거동에 관한 연구 ( Experimental Study on Structural Behavior of Concrete-Filled Circular Tubular Column to H-Beam connections )

This paper is an experimental study on structural behavior of Concrete-Filled Circular Tubular(CFCT) column to H-beam connections. The important parameters are the number of inner reinforced rib and the width of H-beam flange(100, 150, 200mm) with variable column thickness(5.8mm, 9.2mm, 12.5mm) around the joint between CFCT and H-beam. Test results are summarized for the displacement, strength, initial stiffness, failure mode and energy absorption capacity of each specimen. The purpose of this paper is to investigate the stiffness and the strength of connections to evaluate the structural behavior of the CFCT column to H-beam connections. Therefore, I would like to suggest the basic data for non-diaphragm connection.
