Continuous beams are an effective and economic solution for large span structures that may be applicable in large production halls or warehouses. For this construction continuous beams are used as the principal load-bearing elements in order to cover large parallel sections of roof. As the moment distribution of continuous beams is excellent, the bending under load and the stress concentration can be optimised. In the case of extremely large spans, joints in the glulam are factory engineered and executed on site in order to facilitate the transport of the individual structural members.
In order to ensure adequate drainage falls over the roof areas, a roof-pitch of between 2 – 5° is recommended. Depending on the application area, the internal columns to sub-divide the space and the principal external columns can be executed in different materials (e.g. fixed ended reinforced concrete internal columns whilst pin-ended timber columns are used around the building perimeter)
