Structural Steel Semirigid Connections provides a comprehensive source of information on the design of semirigid frames, up to the complete detailing of beam-to-column connections. Focusing on the prediction of the moment-rotation curve of connections, it offers procedures for predicting the connection plastic rotation supply. Extensive numerical examples clarify the practical application of the theoretical background presented. With the awareness it provides of the influence of joint rotational behavior on elastic and inelastic responses, this exhaustive reference will greatly benefit researchers, professionals, and specification-writing groups involved with structural steel.
