This video clearly explains how to analyze a continuous beam having 3 spans by slope deflection method. The beam is having Fixed support at one end and other three supports are roller and hinge.

We start analyzing the beam by finding out fixed end moments for given loadings, than we should check where we can have the rotations in this case rotations will occur at B, C and D points, next we can apply slope deflection equations to calculate end moments, we need equilibrium conditions at the points where moment will be zero, with these conditions we can calculate the unknowns and than substituting back in end moment equations we can get the final moments. Lastly we can conclude the problem by drawing the bending moment and shear force diagram.
