Abstract

Openings on the I-shaped beam web could accommodate pipelines and therefore might cut down the project cost due to the floor height is lower. In this paper, three concrete I-shaped beams are prepared, the sole difference between their is the openings position on the beam web. To compensate the strength undermined by the openings, annular stirrups are added to the surroundings of the openings. Then, based on these preparation works, a series of experiments were carried out to test the shear behavior of the beams and obtain relevant data, such as deflection, crack width and distribution, strain of reinforcing steel. Data analyses were made according to the statistics collected from the experiments what testified the feasibility of extending the opening at the beam web’s ends. Some useful proposals about how to decide the bar amounts of annular stirrups also given by this work.
