Strap Beam Supporting on Inner Wall. There may not be inner columns always close by or perpendicular to support the strap beam. Therefore, we have to support the beam with whatever element is available. These strap footing types are also not widely seen in construction. When there are reinforced concrete walls, we support the strap …

A carbon fibre reinforced polymer (CFRP) strap system has been identified as a promising method for retrofitting existing reinforced concrete (RC) structures. The CFRP straps, which can be prestressed, act as additional transverse reinforcement and have been shown to increase the shear capacity of RC beams. Since the straps are unbonded, the strap …

So that d = 525 - 46 = 479 mm Maximum shear resistance VRd2 = 0.3vfckbd where v = 0. 7 - fck/200 = 0.575 Therefore VRd2 = 0.3 X 0.575 X 25 X 230 X 479 X 10-3 = 475 kN Hence v = 107kN < …
