Effect of an Opening on Reinforced Concrete Hollow

The effect of the opening section size on the behavior of hollow beam is also evaluated. The openings created in the web of hollow beams led to a decrease in beam capacity although the hollow beam with small opening can carry almost the same load as that of hollow beam without an opening. The result also shows that the capacity of UHPC beams for twisting is twice that of HSC beams. Keywords: Cyclic load; Flexural load; Finite element; Hollow beam; High-strength concrete
