Abstract
In this paper, two dimensional non-linear finite element (FE) analyses for RC shear walls with multi-openings were conducted to investigate the shear force contributions and internal stress transferring mechanisms. Parametric analyses were also conducted for the shear walls with several opening layouts. The analytical results showed that diagonally compressive struts transferring shear forces were formed in each wall element and the shape depended on the wall panel length, regardless of opening layouts and loading directions. On the basis of these analytical results, the simplified shear resistant model of the shear walls with multi-openings was constructed. It is clarified that the shear strength of RC shear walls with multi-openings can be evaluated by the proposed simplified model.
