Answer 1

Explanation:

Let a two-span continuous beam, shown in the figure below:

Slope deflection equations

For span AB:

Where Mf_AB = Fixed end moment at A for span AB

θ_A = Slope at A

θB = Slope at B

Δ = Settlement of support.

For span BC:

There will be 4 Nos. of slope deflection equations, for a two-span continuous beam.
