Abstract | The study combines dynamic programming and human interaction to optimize the configuration of truss structures based on either the minimum weight or the minimum cost, with consideration of other nonquantifiable factors such as style , aesthetics, practicality etc. The procedure which has been implemented into package is divided in to two parts: a computer (1 ) The dynamic programming employs the vertical truss coordinate of upper - chord join t as one state variable . The optimization is decomposed into stages, extending from a support, one panel (stage ) at a time, During each stage , the AISC-1970 structural steel design code, which considers stability and yield effects, is employed . The optimization is carried out stage by stage until the overall optimal cumulative return is obtained at the fi n al stage. ( 2 ) The graphic displays of candid ate truss configurations a nd their corresponding objective functions and deflections allow the user to interact and make decision on his choice of final optimal structure among them after considering other non-technical aspects of design such as style, aesthetics, practicality and even his personal taste . This optimization procedure is especially efficient for problems of which the variables are discrete. |
