In the slope-deflection method for a prismatic beam member, fixed-end moments are added to the rotational stiffness terms mainly to represent:
Choose the correct answer
the effect of intermediate member loads when member ends are restrained
the self-weight of the joint panel only
the reduction of modulus of elasticity with time only
the elimination of all support reactions from equilibrium
Correct Answer
A. the effect of intermediate member loads when member ends are restrained

Member loads between the joints create fixed-end moments. The slope-deflection equation superposes these load effects with end rotations and joint translation effects.
