Unformatted text preview: cements caused by these forces to be treated separately and then added together.
The principle of superposition is valid as long as: The displacements are linearly related to the loading. The loading does not significantly change the original geometry or configuration of the member. Flexibility Analysis Flexibility Analysis ► ► ►
► ► The Flexibility Method or Force Method of Analysis uses the principle of superposition to solve the statically indeterminate problem.
In this method, a redundant support is removed so that the member is “free” to distort due to the application of the external forces. Draw FBD for this case.
The equations of compatibility are written for the “free” condition.
Next, remove the external forces and add the redundant reaction force acting on the member. Draw FBD for this case.
Determine the equations of compatibility due to the redundant force and use the superposition principle to solve for this force. E...
