Steel Beam Connection Calculations - What we can do
At beamcalc.co.uk we offer accurate and reliable steel beam connection calculations that are in full accordance with Eurocodes or British Standard 5950-1 and are suitable for Building Control approval. Whether you require simple shear beam connections or full moment beam connections we can help you.
Our steel beam connection calculations are essential structural engineering calculations which are used to design and verify the safety, strength, and stiffness of the components that join steel members together such as beams, columns, braces, plates, etc…
Our calculations ensure that the bolts, welds, plates, angles, and supporting steel can safely transfer the applied loads. If you are joining structural members together such as steel beams or steel columns your Building Control provider will certainly ask you for the relevant structural calculations.
Our calculation documents contain comprehensive steel connection calculations and detailed steel fabrication details specifying what is required to be made. These are essential documents to give to your steel fabricator and contractor.
What Are Steel Beam Connection Calculations?
Steel beam connection calculations determine whether a connection can safely resist the forces being applied to it.
These forces usually come from beams framing into columns or other beams.
The calculations check:
1. Bolt Capacity
-
Shear capacity
-
Tension capacity (if moment or axial forces exist)
-
Combined shear + tension
-
Bolt bearing on plates or beam web
2. Weld Capacity
-
Fillet weld shear
-
Groove weld moment or axial capacity
-
Weld group analysis if loads produce moments
3. Plate / Angle Strength
-
Plate shear yielding/rupture
-
Plate bending
-
Block shear failure
-
Local plate buckling
4. Beam Web/Flange Strength Near the Connection
-
Web yielding
-
Web crippling
-
Web buckling
-
Flange local bending (especially in moment connections)
5. Connection Stiffness
For moment connections or partially restrained connections, stiffness is also calculated.
Why steel connections Matter
Connections are often the most complex part of a steel structure because:
-
They must transfer load safely.
-
They are often the weakest part if not designed properly.
-
A structure can fail at the connection even if the beam itself is very strong.
