Simple structural steel beam calculations and column calculations can usually be completed with a 3-5 day turnaround. Often our engineers do not need to visit the installation site ensuring costs are kept to a minimum.
If further design work is required we can provide detailed drawings for layouts, roof structure and window & door placements if required.
If you simply want advice we are happy to help.
What is a Beam Design?
Beams are designed to support mainly vertical loads and are small in cross-section compared with their span. A beam is a structural member which spans horizontally between supports and carries loads which act at right angles to the length of the beam.
The detailed behaviour of a beam is complex and exact analysis requires considerable mathematical sophistication. However, the vast majority of beams can be designed using engineering beam theory. This is based on a number of simplifying assumptions. Engineering beam theory identifies two types of internal force – bending moments and shear forces. the behaviour of any beam is characterised by the magnitude and distribution of these forces.
Beams deflect when loaded and this must be limited to avoid damage and distress. Beam deflections can be calculated and depend on the modulus of elasticity of the material, and the moment of inertia of the cross-section. In general, the calculation of deflection is not straight forward. However, algebraic expressions are tabulated for many standard cases. The deflection of a particular beam is inversely proportional to:
- modulus of elasticity
- moment of inertia
The modulus of elasticity is constant for all structural steels so the larger the moment of inertia the smaller the deflection.
