Flat beam structures are the most suitable option, when there is a need for a limited amount of space within a specific range. The depth of the beams is consequently directly proportional to the span that can be supported, and for glue-laminated beams and steel girders, this requires a depth-to-span ratio of around 1:20 for typical loads. Despite the fact that solid web beam systems have a depth to span ratio advantage, they have a high self-weight and do not easily accommodate mechanical services as do open-web or trussed beam structures.
