Elastic-Plastic Connections with Limited Capacity of Positive Moment

In this type of connections it is assumed that positive moment is limited to M+m but it is not limited in negative direction. If we use the same unit moments that was used in the previous section, similar formulation can be derived except that to keep unique coordinate system there will be a negative sign in behind of X – . In this case the sub-problem Eq. (8) will be as in Eq. (9)
