Abstract:

One of the reasons that steel is preferred for carrier system material is due to its high strength and ductile behaviour. Deformation capacity and the ductile behaviour of steel structure components depends on a suitable design. However, steel structure components may face stability problems due to being exposed to high out-of-design loads. For steel structures, this condition can be observed while beams of the steel structure is under bending effect on their strong axis and is also exposed to lateral loading. If this stability condition is not prevented, the system will undergo plastic deformation into a failure state and lateral buckling will occur. Mentioned condition may cause the steel carrier system with high ductility properties to display brittle behaviour. In this research paper, the effect of lateral load on the capacity of a I beams under bending effect is investigated. In the study, beams with different section and span properties are exposed to different loads. In this context, in order to determine the effect of lateral load on the capacity, 19 different models with 11 different loads on each model are analysed using Ansys Workbench finite element program and the results are presented comparatively.
