  • Abstract The structural behavior of steel reinforced members is dependent upon the effective integration of structural steel and the reinforced concrete. In order to achieve the design performance, the SRC section must maintain its integrity without premature cracks. However, in tall building construction, the need for service ducts makes it inevitable to open the web of such members. This opening affects the integrity of the SRC section and reduces the strength and stiffness of the member to different extent, when the sizes of the opening vary.
    This research is focused on the experimental study of steel reinforced concrete members with web openings. Relationship between member strength, stiffness and sizes of opening was discussed. Methods for strengthening the web-opened members were proposed. Performance of strengthened members is also reported.
