In the slope deflection equations, the deformations are considered to be caused by
i) bending moment
ii) shear force
iii) axial force
The correct answer is
A. Only (i)
B. (i) and (ii)
C. (ii) and (iii)
D. (i), (ii) and (iii)
Answer: Option A

In slope deflection method following assumptions are made:-
1.all joints are rigid
2.Axial deformation are neglected
3.shear deformations are neglected
Assumptions 2&3 are reasonable because distortion of rigid jointed structures due to axial forces and shear forces are very small compared to distortion due to flexure
Hence on bending moment deformation is considered
