BEHAVIOUR AND STRENGTH OF RC BEAMS WITH REGULAR TRIANGULAR OR CIRCULAR WEB OPENINGS

The behavior of rc beams with regular web openings subjected to monotonic loading is investigated experimentally. thus, six beams with regular triangular or regular circular big openings and three reference beams without openings are tested. the test parameters are chosen as the geometries of the openings and the reinforcement ratios at the tension zone. the test results show that beams with low reinforcement or normally reinforced at the tension zone behave in a sufficiently ductile manner. a general observation is that, beams having circular openings yielded better results than the beams with triangular web openings.
