A stiffness matrix is to be generated for beam AB as a horizontal flexural member. As per the method adopted for calculation of stiffness matrix, if end A is given translational displacement in a vertically upward direction, the end forces generated at the end ‘B’ are
  • a)
    No force at end B
  • b)
    -12EI/L3 vertical force and 6EI/L2moment
  • c)
    -6EI/L3 vertical force and 2EI/L moment
  • d)
    -6EI/L2  vertical force and 4EI/L moment
Correct answer is option 'B'. Can you explain this answer?

Concept:
Stiffness Matrix:
The elements of the stiffness matrix are the forces that are required to hold the restrained structure with a unit displacement at one of the coordinates and with zero displacements at all other coordinates are determined.
Hence,
For the fixed beam shown below -

Let, the end A is given translational displacement in an upward direction keeping all other coordinates fixed,
The following figure shows the forces required to hold the structure in the given position -
Hence, from the above figure, the end forces generated at B are -
  • Vertical force = 12EI/L3 (Downward) = - 12EI/L3
Negative sign because opposite to the direction of displacement.
  • Moment = 6EI/L2 (Anticlockwise)
