The course objective is to provide a comprehensive introduction to the different methods of analysis of composite steel-concrete structures according to the theory of viscoelasticity and theory of plasticity considering geometrical nonlinearities.  

Students will be able to understand and apply existing and develop new theoretical and numerical models for analysis of composite and prestressed structures.

Viscoelastic properties of concrete and relaxation of prestressing steel. Creep compliance function according to the aging theory and hereditary theory. Definition of linear integral operators and their application in linear viscoelasticity. Integral relation between concrete and prestressing steel stresses and strains and their presentation using linear integral operators. Mathematical theory of analysis of steel and concrete and prestressing structures. Stress based and displacement based analysis methods.

Simplified analysis methods. AAEM method. Analysis according to the theory of plasticity and limit states. Time dependent deformations of concrete and concrete cracking. Analysis of continuous composite beams. Selected topics of analysis of composite columns.
