기둥단면형상에 따른 무량판구조시스템 강성변화에 관한 연구

In the present study, design methodologies for effective width of slabs in slab-column connections were evaluated in comparison with the experimental results on the full-scale slab-column connections. The design methodologies are as follows: the methodology proposed by Jacob S. Grossman and the metholodogy prposed by Choi&Song. The former does not predict the stiffness change of the slab-column connetion due to the change in the column section in th loading direction is long. Accordingly, the equation to calculate the effective width of slabs should be modified to reflect the effect of the change in the column section shape.
