Compatibility Relation for Indeterminate Beam Problem

The compatibility relation that can be used to solve the indeterminate beam problem is based on the principle of continuity of deformation.

When encountering an indeterminate beam problem, it is essential to understand the concept of continuity of deformation. This principle emphasizes that the deformation of the beam must remain consistent and continuous throughout its structure, especially at points where it is not fixed.

For the specific case mentioned in the data, the compatibility relation is determined by certain conditions:

• The angle of rotation at B (θB) is equal to the rotation angle of the torsional spring.
• The angle of rotation at A (θA) is zero.
• The deflection at A is also zero.

By adhering to these compatibility relations, we can effectively solve for the unknown variables in the indeterminate beam problem, such as bending moment and shear force at different points along the beam. This approach ensures accurate calculations and understanding of the beam's behavior under load, ultimately preventing failure.
