Fundamentals of the Flexibility Method
Basic concepts of the flexibility method (also called the force method) are described in this chapter. The flexibility method is a generalization of the Maxwell-Mohr method developed by J. C. Maxwell in 1864 and O. C. Mohr in 1874. In this approach statically indeterminate structures are analyzed by writing compatibility equations in terms of flexibility coefficients and selected redundants. Also involved in such equations are displacements calculated for a statically determinate version of the original structure (with the redundants released). Because the flexibility method requires extensive use of calculated displacements, the material in Appendix A will be referenced frequently.
