A new class of evolutionary methods based on the concept of transferred force for structural design
The concept of Transferred Force through certain parts of the structure to its supports is explained. Methods for topology design of linearly elastic structures based on the concept of Transferred Force are studied. The methods do not require any formal optimization techniques, and so they are quite simple to use. A nondimensional parameter that indicates overall performance of the structure is defined and monitored during the redesign process. The methods are applied to truss structures and 2-D plates. Improved shapes and topologies are obtained from the viewpoint of force transfer. Final designs have larger Transferred Forces, implying that the remaining members or elements of the structure contribute optimally to force transfer. It is concluded that the concept of Transferred Forces for redesign of structures is a viable approach and should be developed further for practical applications.
