From the image you have it seem they use 'moment release' as pin joint . Let's say the beam was twisted a bit in the shipping. So the support will have moment and shear in both y-y and z-z directions. I think what they say by moment end release is the Moments are set to zero, not carried to the joint but the shear is. In practice end release is removing the support at the joint. In some methods you release the end like a cantilever and then apply forces to bring it back to geometry of the joint constrain. | |

It appears that the OP is working through those statics that you mentioned, and your answer could afford to go into more detail to provide more explanation. | |

It is assumed that the questioner has the minimum knowledge to be familiar with the basic ideas. Here is just a few examples of joint release: Total release, removal of support. Moment release, joint is pin connected. Shear release, the joint is on rollers in the direction where moment is allowed, like a drawer on rollers which can't tip over. torsion release means member can roll at joint but is constrained otherwise. Like a car antenna's base connection. | |
