How EuroBeam analyses beam web openings
EuroBeam beam web opening checking is based on SCI publication P355 Design of Composite Beams with Large Web openings (ISBN 2011 978-1-85942-197-0) and if you are going to use this option you are strongly advised to obtain a copy. The routine works in a very similar to the beam web opening checking in ProSteel (based on Design for openings in the webs of composite beams, CIRIA Special Publication 51), but there are a few differences:
- There are explicit options for circular and elongated circle openings, rather than them needed to be entered as equivalent rectangles.
- A small diagram at the top of the printout shows the positions of the openings.
- The rules re size and positioning of openings have changed slightly from previous SCI guidance
- The treatment of stiffened openings has changed slightly - previously stiffeners were ignored when calculating the axial capacity of the top and bottom tees (which determine the moment resistance at the opening)
