Abstract

Short-term allowable shear force of RC multi-story walls for safety assurance and damage control was specified in AIJ standard. However, this allowable force for multi-story shear walls with door openings was defined by limited data. In this study, based on the experimental results of five 1/4 scale multi-story shear wall specimens with various disposition of vertically aligned door openings, several strength reduction factors related to door openings were verified for the short-term allowable force based on the observed strengths for safety assurance and the observed residual crack widths for damage control. Consequently, an optimal reduction factor was suggested.
