Shear Behavior of R.C Beams Strengthened Using NSM Pre-stressed Bars
This study attempts to understand the shear behaviour of externally pre-stressed R.C beams using NSM pre-stressed bars. Nine reinforced concrete beams of cross-section 150 mm width, 300 mm overall thickness and 1400 mm total length were fabricated and tested under three point loads. One of these was fabricated without strengthening while the others were strengthened to study different parameters; damage ... إقراء المزيد
