Truss design by topology optimization

With the exception of the pioneering work of michell, truss design has been generally restricted to optimizing member cross section and geometry. There has been some work on simple topology generators based on heuristics. Single attribute objective functions have always been used. In contrast, a method for truss design in which the topology of statically determinate trusses can be freely manipulated and the design optimized for topology, geometry and discrete member sizes for a multi attribute objective function whose attributes include weight, cost of members and cost of fabrication, is presented. Dynamic programming using the delayed decision technique is employed to carry out the discrete multi attribute optimization. This approach has been embodied in a computer program and results for a particular case are presented (a).
