Simplified v
ersion of
the design method according E

AG
001,
TR
029. Design resistance according data giv
en in
ETA-07/0260, issue
2009-01-12.
Influence
of concrete strength
Influence
of edge distance
Influence
of
spacing
Valid for a group of two anchors.
(The method may also be applied for anchor groups with more than two
anc
hors or more than one edge distance.
The influencing factors
must then be considered for each edge
distanc
e and spacing.
The calculated design loads are then on the sav
e side: They will be lower than the
exact v
alues according ETAG
001,
TR
029.
To av
oid this, it is recommended to use the anc
hor design
software PROFIS anchor)
The
design
method
is based on
the following
simplification:
No different
loads are acting on indiv
idual
anchors (no ec
centricity)
The v
alues are v
alid for one anchor.
For more complex fastening applications pleas
e use the anchor design software
PROFIS Anchor.
