Seismic design
PROFIS Anchor 2.4 I MKT E2/CM/MMA I June 2013 5 www.hilti.com/seismic
Seismic anchor design as per technical report EOTA TR 045
• All the documents on anchor design are under revision and will be published as part 4 of Eurocode 2 (EN 1992-4).
• Publication of EN 1992-4 is expected in 2014.
• In between, EOTA members have prepared technical report EOTA TR 045 to allow seismic anchor design (technically approved, waiting official publication).

Selecting the seismic performance category
7 www.hilti.com/seismic PROFIS Anchor 2.4 I MKT E2/CM/MMA I June 2013
Two seismic performance categories (C1,C2) are defined by the Annex E of ETAG 001
• The new ETAG Annex E regulates the assessment of anchors intended to be used to sustain seismic loading
Seismic performance category C1 • Similar to the current
american approvals • Less demanding for anchors • Uniquely for non strucutral
applications
Seismic performance category C1 • Essays more demandings
with cracks of 0,8mm • Mainly for structural
applications

Options et critères de conception
12 www.hilti.com/seismic PROFIS Anchor 2.4 I MKT E2/CM/MMA I June 2013
Design approach
a) Ignoring the anchor ductility a1) Capacity Design
• anchors must resist to the load corresponding to the yielding or failure of the attachment
a2) Elastic design • anchors must resist to the load resulting from an elastic seismic
design − structural elements behavior factor q = 1.0 − non-structural behavior factor qa depending on the non-structural element
13 www.hilti.com/seismic PROFIS Anchor 2.4 I MKT E2/CM/MMA I June 2013
Design approach
b) Considering the anchor ductility • Only valid for anchor seismic category C2 • Anchor needs to comply with a list of requirements that to ensure ductility (e.g. stretch length of 8d) • Recommended for secondary seismic members and non-structural attachments, may not be suitable for primary seismic members (considering possibly large non-recoverable displacements of the anchor) • In order to ensure the steel failure, additional checks must be done (comparison between the concrete and steel resistance).

Design parameters
• Seismic performance category • C1 : only resistance at ultimate limit state • C2 : resistances at ultimate limit state AND displacement at ultimate limit
state and damage limitation state • Cracked concrete • Ratio of seismic tension component of the design force to the total
design tensile force or ratio of seismic shear tension component of the design force to the total design shear tensile force
• ≤ 20 % : static design (ETAG 001 Annex C or EOTA TR029) • > 20 % : seismic design (EOTA TR 045)
