철근콘크리트기둥과 철골보 혼합구조형 기둥-보 내다이어프램 접합부의 내진성능 실험평가

다국어 초록 (Multilingual Abstract)

The high-strength development of building materials has enabled the construction of high-rise and long-span buildings, leading to the development of composite structures using steel and concrete to meet the diverse demands of buildings. Among these, the mixed structure with reinforced concrete columns and steel beams is gaining attention for its cost-effectiveness by optimally placing the mechanical performance of the members. However, research on the column-beam joints where columns and beams intersect is insufficient. Therefore, a column-beam joint with an internal diaphragm type, where the steel beam does not penetrate, is proposed. In this study, two full-scale cyclic tests were conducted to investigate the seismic performance of the reinforced concrete column and steel beam joint. The experimental variable was the internal diaphragm connection method. The experimental results showed that the proposed connection exhibited excellent ductile performance.
