Shear Design of Reinforced Concrete Shear Walls with Openings using Strut-and-Tie Models

스트럿-타이 모델을 이용한 개구부를 갖는 전단벽의 전단 설계

This study proposes the design method of the shear walls with openings using strut-and-tie models. Strut-and-tie models are constructed for opening near the middle of the wall and for opening near a wall boundary. These enables an admissible load path for the horizontal earthquake force. These models consider the size and position of opening effectively. Each model is suitable for the seismic response corresponding with lateral forces in a given direction to be considered. The proposed models are good agreements with nonlinear finite element analysis(DIANA) results.
