Otimização geométrica de treliças

A computer system for automatic optimization of truss geometry is proposed, based upon Fletcher and Reeves algorithm. The system applies to space trusses, with multiple loading conditions and the following constraint types: - Geometric constraints: minimum and maximum values of joint coordinates, joint symmetry and variation of joint positions along fixed lines. - Behavior constraints: allowable member stresses (including buckling) and maximum joint displacements. Methods of structural analysis and the optimizatio algorithm are thoroughly discussed. A flowchart displays the general system organization. ln addition, examples - some of them of structures already built - are included so that the system efficiency can be verified.
