Description

In this study, proposing reinforce method for main-girder in T-beam, which sectional width is small. Proposing reinforce method of process is that, buring steel bar into RC-beam axial vertical direction, and acting its on tension forces. As a result, compression force acted on RC-beam across axial direction, and accomplished shear reinforcement.<br>Carrying out bending test for non-reinforced RC-beam until shear fractures occurred. After reinforcing shear fractures occurred in RC-beam, carrying out bending test again. Furtheremore, carrying out bending test for reinforcing RC-beams which varing torque for stell bar.<br>As the results of bending test, when compressive force across beam-axial direction acting on RC-beam, load carring capacity increased, and its toughness improved remarkably. Furthermore, occurring fractures were almost bending fractures, and shear fractures are not occurred around reinforcing points in RC-beam, which embedded in steel bar acted on 100[N⋅m] torque. Terefore, it is thought that proposing reinforce method function effectively to shear reinforcing.
