기둥 형상에 따른 Wide Beam-기둥 접합부의 이력거동에 관한 연구

In this paper, the effective width of wide beam with variable column section was investigated experimentally. Three specimens with variable column sections were designed to represent the exterior wide beam-column joint and incremental cyclic loads were acted to the beam. Test result showed that the strength of beam was increased when the section size of column was enlarged. In case of the enlargement of column depth, especially, the strength was maximized. On the comparison of Wight's and Newzealand code formula with test results, it was concluded that these two formula underestimated the effective width of wide beam.
