The authors have been studying the column-through type RCS (reinforced concrete plus steel) joints composed of web panel with opening, cover plate and triangle stiffener. The previous paper reported the relationship between shear strength and deformation capability of the RCS joint. The present paper addresses the investigation on the influence of stresses from the steel braces upon the joints, through loading tests conducted on a two-story, two-span RCS structure with steel braces. In addition to these tests, static elasto-plastic analysis was implemented, using the shear strength and shear deformation model proposed by the authors. The study results demonstrated that the stresses from the braces do not exert significant influence on the joint behavior and the analytical results agreed very well with the experimental results.
