Shape and discrete sizing optimization of timber truss girdersŠilih, Simon ...This paper shows the shape and discrete sizing optimization of timber trusses with the consideration of joint flexibility. The optimization was performed bythe Mixed- Integer Nonlinear Programming ... (MINLP) approach. In the optimization model an economic objective function for minimizing the structure's self-manufacturing costs was defined. The design conditions in accordance with Eurocode 5 were considered as optimization constraints. The internal forces and deflections were calculated by finite element equations. The structural stiffness matrix was composed by considering fictitiously decreased cross-sectional areas of all the flexibly connected elements. The cross-section dimensions and the number of fasteners were defined as discrete sizing variables, while the joint coordinates were considered as continuous shape variables. The applicability of the proposed approach is demonstrated through some numerical examples presented at the end of the paper.Vrsta gradiva - prispevek na konferenci ; neleposlovje za odrasleLeto - 2009Jezik - angleškiCOBISS.SI-ID - 13414166
