Development of a calculation tool for connections with lateral load-carrying metal fasteners (English)
Abstract [en]

The governing set of regulations for structural engineering in Sweden used to be Boverket, BKR. However in the beginning of the 21st century a changeover to new regulations, the Eurocodes, started.

The transition was completed in year 2011 when the Eurocodes became the mandatory design work policy for all countries within the European Union. The Eurocodes were implemented to simplify and remove potential barriers to trade that may exist when countries have different design rules.  Since the changeover it has been important for all construction companies to update their knowledge base and their design software.

When comparing the two calculation processes they seem similar, but there are a couple of differences worth noting.  With the new regulations, engineers will find that the process when designing joints in timber structures has changed.  What used to be a fairly easy and straight forward calculation procedure has now become tedious and time consuming.

The objective of this degree project is to present a product, a dimensioning tool that will help structural engineers when computing lateral load carrying joints in timber structures.

The degree project is made up of two parts where the first part is the written report describing the background and theory behind load carrying computations. The second part of the project is the actual dimensioning tool which includes several worksheets in Microsoft Excel. The program treats single and double shear connections of the following:

  • Nail joints
  • Screw joints
  • Steel plates (thick and thin types)

 The user can edit the following parameters:

  • Type of plate/ number of shears
  • Strength class of timber members
  • Member and plate size
  • Type of fastener
  • Diameter of fastener
  • Length of fastener
  • Yield moment of fastener
  • kmod and partial factors for design load carrying capacity

The dimensioning tool was created and developed in collaboration with structural engineers at the company Byggteknik AB. By request, a results documentation sheet was developed with intended use for project presentations and project reviews.
