Dear All,

How to draw a Shear force diagram and Bending moment diagram for a fixed beam with internal hinges at the center?

Please find the attached image for your reference.

Thanks & Regards,
Ramu.

This is generally hypothetical structural problem,, may be for academic interests.

This beam having internal hinge at center :-
It is equivalent to two nos cantilever beams from fixed supports.
If L is spsn of beam ,, half span on each side is L/2 .
BM for udl will be zero at center and  increasing in parabolic profile at support = w((L/2) ^2) /2 just same as that of cantilever

SF is again max support decreasing linearly to zero at internal hinge.

May be i am,, by now,, naive about very basics  , and request to be corrected,,
