  • Welded splices

  • Portal apex haunch

Angle cleat connections

  • Single angle web cleats

  • Double angle web cleats

  • Double flange cleats

  • Clip and seating angles

Welded moment connections

  • Full strength connections,  butt welds / fillet welds

Column bases

  • Nominally pinned bases

  • Moment-resisting bases

Fin plates

  • Single fin plates

  • Double fin plates

In our connection design process, we utilise two different analysis methods: the finite element method, using specialised software; and the standard component method using our internal advanced spreadsheets. Each method allows us to independently asses the capacity of the whole joint or the most important components of connection to ensure that the design produced by each method is adequate and safe.
Finite Element Method (FEM):
Connected members and all parts of a connection: bolts, welds and plates are modelled in a dedicated software incorporating finite element analysis. We can analyse all types of connections ranging from simple to any complex, bespoke and non-standard joints in a fairly short period of time. All checks are performed in accordance to Eurocodes, namely: BS EN 1993-1-1:2005; BS EN 1993-1-5:2006; BS EN 1993-1-8:2005.
Component method with our in-house spreadsheets:
Connection design calculations are produced in accordance with the latest relevant standards and publications including: SCI P358 Publication and SCI P398 Publication. With this method we use self-prepared advanced spreadsheets which were created after a thorough study of all formulas and equations contained in a wide range of design standards, technical books, articles, publications as well as our own experience: 
  • BS EN 1993-1-5:2006
  • BS EN 1090-1:2009+A1:2011 and BS EN 1090-2:2008+A1:2011
  • NA to: BS EN 1993-1-1:2005, BS EN 1993-1-5:2006, BS EN 1993-1-8:2005
