To fully realize the potential of truss layout optimization for the design of lightweight structures, the consideration of geometrical variables is then introduced.Chapter 2 addresses truss geometry and topology optimization by combining m 410 0$aFocus series in numerical methods in engineering. 410 0$aFocus series (London, England) 606 $aStructural engineering$xMathematical models 606 $aBuilding materials 606 $aLightweight construction 606 $aSpace frame structures$xMaterials 606 $aStructural design$xMathematics 615 0$aStructural engineering$xMathematical models. 615 0$aBuilding materials. 615 0$aLightweight construction. 615 0$aSpace frame structures$xMaterials. 615 0$aStructural design$xMathematics. 676 $a624.1 700 $aDescamps$b Benoi?t$0989965 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910821107603321 996 $aComputational design of lightweight structures$94019523 997 $aUNINA
