hi  i think that a notch is a cut that you do on a beam usually on the compresion face of the   
hi lgross,
ok a notch is a cut. you have quoted is a singly notched end how about doubly notched ends for a i beam, do you mean we cut the top and bottom flanges? can you also give an example of doubly notched ends steel   
i am not familiar with the specification reference you use.
i suspect this may be a reference to a "cope" at the ends of a steel beam.  in bolted sections, we often cope the top and/or bottom flanges to eliminate geometric interference with the attaching   
i believe a double notch occurs when you have two beams of the one size framing into each other. the top and bottom flanges would clash unless the end of one beam was cut back at the flanges.
as dinosaur said, this is usually called a cope in the usa and australia.
in the uk it is then typical to weld an end plate to the end of the 'coped' (or notched) beam to take the bolts.
the united kingdom sci has a publication of standardised connections which will include examples of this as well as capacities.
design (in uk) of beam notched end can be found here;

hi apsix,
what does ncci stand for and what is its homepage? thank you.
dcnnng,
from the sci (steel construction institute) site;
"design verification for the eurocodes will cover the four critical steps:
each design and each design activity will be described separately by a flow chart;
a commentary will be provided on the effective application of every clause in ec3 and that is referenced;
non-contradictory, complementary information (ncci) fff">will be presented that addresses all the information that the eurocodes do not cover that is essential for design;
looks like it's part of the campaign to get british designers familiar with eurocodes.
