콘크리트충전 각형강관 Beam Column의 내력 제안식 ( The Formula Suggestion of Concrete Filled Tube Beam-Column Strength )

The objective of this study is to suggest the formula of concrete filled tube strength of beam-column by using of numerical analysis and tests. The formual of LRFD and Limit State Design of KOREA underestimate the concrete filled tube strength from numerical and experimental results. Coefficient is used to evaluate the beam-column strength to apply to the Limit State Design code of KOREA. The effect are compared with numerical analysis results.
