Required rotation of composite connections

According to the method developed previously for calculating the required r otation for composite connections, typical cases are studied and the requir ed connection rotations are evaluated. Maximum span:depth ratios are presen ted so that the required connection rotations are smaller than 20, 25 or 30 mRad respectively. Conclusions are made on the effects of different load c ases, steel grades and end conditions on the required rotation for plastic design of semicontinuous composite beams.
