ABSTRACT
The flexibility method has already been used in Section 4.6 to solve simple statically indeterminate structures. Here, the formal steps implied in that section will be discussed more fully so that the method can be extended to structures having many redundancies. As in the discussion of the stiffness method in Chapter 7 the description of the flexibility method will be based on plane structures having only prismatic members of material obeying Hooke's law and it will be assumed that all loads are applied at joints. If the loads were not applied at joints the solution would be carried out in accordance with the approach of Section 7.15. The principle described in that section is a general one, and is independent of the analysis !'1ethod used.
