A. The centre of gravity of the load system is midway between the centre of span and wheel load under consi-deration
B. The centre of span is midway between the centre of gravity of the load system and the wheel load under consideration
C. The wheel load under consideration is midway between the centre of span and the centre of gravity of the load system
D. None of the above
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
