Question

A fixed beam of span \(L\) rises by \(\Delta\) upwards at right hand support. The fixed end moment at right hand support will be

• A. \(\dfrac{6EI\Delta}{L^2}\) clockwise
• B. \(\dfrac{6EI\Delta}{L^2}\) anticlockwise
• C. \(\dfrac{3EI\Delta}{L^2}\) clockwise
• D. \(\dfrac{3EI\Delta}{L^2}\) anticlockwise

Hint:

Support settlement in a fixed beam: \[ \boxed{ M=\frac{6EI\Delta}{L^2} } \] The direction depends on whether the support rises or settles.

Answer 1

The Correct Option is A
