(b) Secondary beams (460UB67.2 Grade 300plus) are composite beams. i. Determine the effective breadth of concrete flange ii. Determine plastic moment capacity under full shear connection. iii. Determine the kl for the shear studs. iv. Determine if the secondary beams have a "full shear connection". v. If transverse reinforcement provided N10-300mm c/c top and bottom, determine tu.
