Castellated beams are widely used structural elements. The obvious advantage offered by their openings is that utilities and services can pass through them without increasing the overall floor height. As such, they can be easily hidden in the ceiling, leading to an aesthetically pleasing result.
 
However, this convenience comes with a cost. The available calculation tools and manufacturing datasheets have geometric limitations due to the underlying calculation methods. In this webinar we will discuss the recent advancements in this field and how the novel CBFEM can be applied to tackle almost any limitation safely. We will explore the available modelling options for the introduction of boundary conditions and their impact on the analysis results. Lastly, we will explore the available types of analysis and their range of application. Specifically, material non-linear (MNA) analysis, geometrically material non-linear analysis with imperfections (GMNIA) and lastly the eigenvalue stability analysis.
