Abstract

publisherIn order to investigate the effect of R/C framed shearwalls with an opening, we conducted the lateral loading tests on ten shearwalls with an opening of 1/4 scale model. The opening rate was 0.28. The experimental variables included in the test series were the opening position and failure mode. The failure modes of shear walls with an opening were the shear and flexural shear. The reversed cyclic lateral load under a constant axial load wereapplied to the specimens. The lateral load carrying capacity of shear walls with an opening subjected to the lateral load at the Central opening larger than that at unevenly distributed. Also, the capacity of shear walls subjected to the observed capacity agreed well with the calculated one by the authors' equation
