THE EFFECT OF OPENING PARAMETER ON THE MECHANICAL BEHAVIORS OF RC BEAMS WITH LARGE RECTANGULAR OPENINGS

Adopting the concrete model accounting for plastic behavior caused by damage, finite element modeling can stimulate the whole loading process of RC beams with openings. Through a parametric study on the mechanical behavior of beams, the effects of length, height, position of openings on the ultimate capacity and the stiffness of beams are investigated. Some useful suggestions on collocation of openings are proposed.
