Steel Structures

This book presents the structural analysis and design of steel structures using finite element methods (FEM). 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 concentrated on significantly. In this context, design procedures for stability according to the standard Eurocode 3 is introduced and discussed. In addition, important fundamental issues are covered, such as the determination of cross-section properties as well as the elastic and plastic cross-section resistance. Complementary, finite element procedures for cross sections are dealt with, which will have an increasing importance in future. For practitioners in construction engineering as well as for students, an introduction and all necessary calculations for the design of steel structures according to the Eurocodes (EC 3) are presented. In addition, the determination of the limit load capacity of columns and beams subject to stability according to the flow-zone theory is treated in detail, as it is to be expected that this calculation method will be increasingly used in the future in the field of building practice. For this second edition, more calculation examples were worked out and deepened.
