For architectural reasons, sometimes a curved beam forms part of the building design. The curvature induces torsion in horizontal beams and axial loads in vertically curved beams. Therefore they need to be designed specifically for this purpose. Beams can be designed with curves either on plan or elevation. There will be a minimum bending radius for all curved beams, which also needs to be considered.
Our structural calculations for curved beams includes the design of any necessary padstones and connections. Our structural design is for UB's, UC's and RHS sections only.
We need the following information to design a curved beam:
architectural layouts and elevations, or sketch drawings with dimensions, so we can work out all the loadings on the beam
details of the type of construction (concrete or timber floors, brick or block walls etc)
details of any restrictions on the maximum depth of the beam
All design work is carried out in accordance with BS5950 (The structural use of steelwork) and BS5628 (The structural use of masonry).
The calculations provided will be suitable for Building Regulation approval.
