to-beam joints of Figure 9.6a and b. Common arrangements of beam splices are
given in [2-9] and discussed in Sections 9.5.8 and 9.5.9.

9.3.2 Joints for moment transmission

force transmitted by the joint is sufficiently small for it to be neglected in design.

9.3.3 Force and moment joints

A force and moment joint is required to transmit both force and moment, as
in the beam-to-column joint shown in Figure 9.7. Other examples include the
