In timber design, beams are often built from several timber elements. The individual elements can be connected with glue, nails, bolts, or dowels. A glued connection is to be assumed as rigid. In the case of dowel‑type fasteners, the joint is compliant (slip joint), and the cross‑section properties of the connected elements cannot be fully applied.
RFEM 5 allows you to use many different member nonlinearities for designing a model. In the following text, we look at an example of the use of the "slippage" member nonlinearity. The example is a simplified model of a concrete manhole with a square plan view.
Building in existing structures has been always an area of expertise of engineers. Often, additional loads have to be added to existing buildings. In this case, steel girders with end plates and dowel connections are frequently used.
When designing column bases, high-performance anchors are often used for an anchorage. This article describes different models for a column footing and the evaluation thereof.
In RF-/JOINTS Timber – Steel to Timber, you can select a circular connection type for the dowel, bolt, nail, and screw joint categories. For this connection type, the minimum radius is set in compliance with the recommendations of the STEP-1 report of the German Information Service Timber.
In RF‑/JOINTS Timber, you can remove an individual dowel from the calculation, thus creating any dowel layout. The calculation disregards these removed dowels for the ultimate limit state design, as well as for the net timber cross‑section analysis and the rotational spring stiffness determination.
