    Behaviour Of Reinforced Concrete Weak Column-Beam Connections
    (Gazi Univ, Fac Engineering Architecture, 2014) Bakirci Er, Sule; Aykac, Sabahattin; Can, Husnu
    In this study the behavior of RC weak column-beam connections which have no joint stirrups and lack of column stirrups, are investigated experimentally under earthquake loads. Edge beam to column joints were tested under reversed cyclic loads. It is the prestudy of which has seven joint strengthening techniques. 1/2 scaled one reference and seven weak joint specimens with no stirrups were prepared and tested. The building defects in real structure exactly tried to create when producing the weak specimens. These building defects include lacking stirrups in joint region, low compressive strength of concrete and in progress of time pouring out of concrete cover. The weak specimens' behaviors compared with the reference specimen and load-deflection graphics taken. The main parameters are constant axial load and the distance of lacking stirrups at the joint region. As a result of the experimental study in reference specimen achieved to carrying capacity from the beam. Damages in joints are dangerous. In all weak specimens reached to carrying capacity from the joint before the beam. In some weak specimens columns' shear damages and joints' hard damages together determined the carrying capacity.

    Flexural Behavior and Strength of Reinforced Concrete Beams with Multiple Transverse Openings
    (Amer Concrete Inst, 2014) Aykac, Bengi; Aykac, Sabahattin; Kalkan, Ilker; Dundar, Berk; Can, Husnu
    Reported are the results of experiments on 10 rectangular reinforced concrete (RC) beams with and without multiple web openings. The effects of opening geometry, the-use of longitudinal stirrups in the posts between the openings, the use of diagonal reinforcement around openings, and the longitudinal reinforcement ratio on the flexural behavior of RC beams with openings were investigated. The stirrups in the posts were shown to have a significant contribution to the ductility of an RC beam with openings if no diagonal reinforcement is used. For the same reinforcement details, RC beams with circular openings were found to have higher load capacities and ductilities than beams with rectangular openings. The experiments indicated that the posts between the openings need to be prevented from undergoing shear failure to avoid Vierendeel truss action and allow a beam to develop its ductility and bending capacity.
