Design a bracket to support a concentrated factored load V 125,000 lb. acting at a lever arm a = 4 in, from the column face. The horizontal factored force Nic-40,000 lb. The bracket is cast after the supporting 12 x 28 in. column is cured and the column surface at the bracket location is not roughened before casting the bracket. The corbel width = 28 in. Use b = 28 in, fe-5,000 psi, fy fy 60,000 psi and Es 29,000,000 psi. Design the bracket using (a) the shear-friction approach and (b) strut-and-tie approach
