Kurzbeschreibung
Das Buch behandelt die praktische Berechnung von geschweißten Stahlkonstruktionen mit der Finite Element Methode und insbesondere den Nachweis gegen Plattenbeulen.
Due to the relatively large slenderness of plated structures, the proof of adequate
buckling resistance is crucial for dimensioning. Plate buckling is a stability problem
of a compression-loaded plate and is generally characterized by failure of the
structure prior to achieving plastic component resistance. The stability verification
of welded plated structures assisted by finite element analysis (FEM) is becoming
increasingly prevalent in applied engineering. The rules and examples given in
this book might illustrate the correct application of the numerical models and give
background information on the FEM-based design of welded plated structures.
Aside from technical background information on calculation methods and
software requirements, modelling, solution settings, evaluation, and verification as
a key part of this manual, benchmark examples and worked examples are given.
They not only allow the user to better understand the procedure and the
background but can also serve as test examples to prove the validity of their own
numerical calculations. We are sure that this manual will contribute to improved
knowledge of the application of FEM for the design of plated structures, and
thereby enhance the acceptance of FEM design in practice.
