Stability of Structures (4cr)

Objective

Students will be able to apply stability theory in structural analysis. Students will be able to determinate buckling load for different bar structures. Students will be able to use slope-deflection and finite element methods in stability problems. Students will be able to recognize meaning of phenomena like torsional- and flexural torsional buckling for column structures and lateral torsional buckling for beam structures. Students knows a plate buckling phenomenon.
