고연성 엔드플레이트 항복형 철골기둥-보 접합부의 설계 개념과 절차

Recently, Studies on end plate connection for beam yield have been active progressed in USA, Japan and Euro etc. These connections are widely used in European countries and USA, and its design and connection details are proposed in Eurocode 3, AISC LRFD, and FEMA 350. Further introduction of the US connection details is expected in the design criteria for beam - column connections to ensure and establish a better seismic performance. In the US criteria detail for end-plate connection, the size of the beam is controlled by guiding failure type of the beam for connections and thicker end-plate is used. FEMA 355D proposed that plastic deformation in the end-plate make ductile capacity and structural resistance. In this study, we proposed that selection of steel type make end-plate column to beam connections of better seismic performance.
