After a short introduction on the basics of the design, this book illustrates the FEM with a focus on internal forces, displacements, critical loads and modal shapes. Next to finite element procedures for linear calculations considering the stress states of normal force, biaxial bending and warping torsion, non-linear calculations and the stability cases of flexural buckling, lateral torsional buckling and plate buckling are concentratBuilding, Iron and steelStructural designFinite element methodBuilding, Iron and steel.Structural design.Finite element method.624.1/821Kindmann Rolf516622Kraus Matthias516623MiAaPQMiAaPQMiAaPQBOOK9911019176803321Steel structures846715UNINA
