Beams and lintels
JS Engineering Design Ltd. can give advice and provide the calculations and details needed for your project, be it a simple beam or a complex framework. See the checklist below.
Beams are members that span across openings and support structure or loading above them. In buildings they are often used to support walls or floors across openings in walls on the floor below. Lintels are short beams used across window and door openings. Posts can be used to support beams and make a frame. These can range in form from balconies to large framed industrial buildings.
Beams are usually in timber, steel or reinforced concrete. Other materials can be used such as aluminium, glass, or reinforced brickwork, but these are more unusual.
Beams generally have to be designed, i.e. the loads carried by the beam calculated and compared with the strength of the beam. Lintels over small openings are generally sized from manufacturers load tables. Other beams have to be individually calculated. As well as the strength of the beam other factors have to be considered. Such as:
This last item can involve following the beam load down through the building to the foundations and can create more calculations than the beam itself! If the beam is to replace an existing wall then the effect of this on the overall stability of the building, and in some cases adjacent buildings, also has to be considered. Walls provide lateral as well as vertical support, and simple beams cannot replace the lateral support afforded by a wall.
|The advantage of framing is that the interaction of the members can be used to provide lateral as well as vertical support. The interaction has to be carefully calculated and the joints detailed to provide the desired interaction.|
