Course Objective

Beams subjected to axial compression and simultaneously supporting lateral loads are known as beam-columns When certain assumptions are made about the naturte of deformation of an elastic system during the change of configuration associated with the buckling mode,the elastic system may be approximated by suitable ansd adjustable parameters that are determined. Using this concept practical approximate methods can be derived and the methodsare presented in the lecture such as Rayleigh coefficient, The Rayleigh-Ritz Method, and Galerkin Method.

Learning Outcomes of the Course Unit

1   In the elementary theory of bending, to give the relations of the stresses and deflections which are directly proportional to the applied loads.
2   Beams subjected to axial compression and simultaneously supporting lateral loads are known as beam-columns.
3   To analyze the Euler column with mahtematical modelling and boundary conditions and find the buckling loads
4   Theory of Energy Methods
5   To give the alternating numerical methods that is used to find the critical buckling loads different elastic systems
6   To compare the results of theoratical and numerical solutions by considering different engineering problems

Planned Learning Activities and Teaching Methods

The course is taught in a lecture, class presentation and discussion format. All class members are expected to attend and both the lecture and take part in the discussion sessions. Besides the taught lecture, group presentations are to be prepared by the groups assigned for that week and presented to open a discussion session.
