Perilaku Mekanik Balok-T Beton Bertulang Hibrida Dengan Bukaan Pada Badan Akibat Beban Monotonik

ABSTRAK Test result on two hybrid T-beams, partially constructed of light weight concrete are presented and discussed M this paper. The specimens were of similar dimensions, subjected to monotonic loading. An opening was provided in the web of the beams, in the high shear region and the high flexural-shear region, respectively. The behavior of the beams are described in terms of their performance with respect to crack patterns, ultimate capacity, mode of failure, stiffness, and ductility. Test results indicate that the ultimate capacity of beams with web opening in the high shear region is lower, however the deflection and curvature ductilities are higher than those of beams with web opening in the high flexure-shear region. Keywords : T-hewn, hybrid reinforced concrete, web opening, monotonic loading, stiffness , and ductilit
