THE procedure usually adopted for the design of a redundant structure is to assume some initial distribution of material and then to stress this by strain energy methods. From the knowledge of the load distribution thus acquired a second structure is designed and stressed and the process is repeated, if necessary, until a reasonably uniform stress is obtained.
