000018490 520__ $$2eng$$aRecently, although lots of studies on Reinforced Concrete beams with web openings have been performed to realize flexible equipment plan for RC buildings in Japan, there are several unclear points, which are especially shear strength of beam with several web openings and flexural performance of beam with web opening at the beam-end. Therefore, shear test and flexural test were carried out in this study. Specimens were eleven beams with web openings. Experimental factors were number of openings, the strength of concrete and amount of the reinforcement for shear test and diameter size of opening, with or without Y-bar and the strength of concrete. All specimens with a beam part and two loading stub at the both ends of beam were 1/2.5 scale and subjected to reversal shear force and antisymmetric moment. As a result, it showed shear strength of beam with three openings was almost the same as that of a beam with single opening. Additionally, although deformation capability after member yielding was improved by Y-bar, the relationship between amount of reinforcement around opening and deformation capability couldn’t be identified clearly.
