Do you want to know about steel screw pull-out strength? We’ll help you to understand how to do it.
How do you calculate it?
The screw pull-out strength is calculated in accordance with section 8.7.2 of Eurocode 5 – Design of timber structures (version UNI EN 1995-1:2009).
What is the result?
The value that you get depends on different parameters. Which ones?
- characteristic thread pull-out strength
- insertion angle against the grain
- density of wood
- pile depth of the thread.
Also:
- the geometry of the screw
– core diameter
– external diameter
What other parameters are good to consider?
In addition to the previous parameters, you should also refer to the screw certificate. In fact, it has the mechanical characteristics of the connection. What else can we report? Also, it can bring specific values for the characteristic pull-out strength for this specific items.
