If the member is hinged at A rather than at B, Equation 2.316 is still valid provided that the subscript A is changed to B. Member with End Restraints

If the member ends are connected by two linear elastic springs, as in Figure 2.120, with spring constants, PkA and Rb at the A and B ends, respectively, the end rotations of the linear springs are MA/PkA and MB/PkB. If we denote the total end rotations at joints A and B by 0A and 0B, respectively, then the corresponding member end rotations, with respect to its chord, will be (0A — MA/PkA) and (0B — MB/PkB). As a result, the slope deflection equations are modified to
