웨브벽체의 형상비가 T형벽체의 플랜지 유효폭에 미치는 영향

This paper deals with the effect of the web wall's aspect ratio to the effective flange width of the T-shaped wall. In this study, the non-linear FEM analysis has been conducted in a parametric way, by varying heigth of the wall, length of the web wall, thickness of the flange wall and aspect ratio of the T-shaped wall. The results of the analysis clearly indicate that the most influential variable on the effective width is the web wall's aspect ratio and most of existing formulae to compute the effective flange width of the T-shaped wall based on a specified variable are not effective, since these formulae do not consider the web wall's aspect ratio. Based on the results of FEM analyses, the method to compute the effective width of the flange wall is suggested, and the validity of the proposed method is confirmed.
