Concrete anchors are widely used in fastening both structural and non-structural elements. Many structural engineers specify post-installed anchors where they design different fastening points with either mechanical or adhesive anchor system in many construction applications.

These elements fastened are somehow directly or indirectly linked to the safety of human being or different economic investments. Accordingly, Seismic design and specification of anchor connections is crucial in both structural and non-structural applications.

Structural connections are vital to ensure that the structure responds to a seismic event in a proper, predictable manner. Connections should, therefore be clearly detailed in the design phase to make certain that both contractors and building inspectors comprehend project specifications.

On the other side, Anchors are often used to fasten non-structural components. Their design and selection is therefore crucial in terms of minimizing both injuries to building occupants and the costs associated with seismic events.

Eurocode 1, Eurocode 2 and Eurocode 8 set the frame of design of concrete structures, while for anchors, European Technical Approval Guideline (ETAG) 001 defines the qualification and design requirement for anchor fastenings. Under seismic conditions, EC8 provides the method to calculate seismic action and structural response while EC2 gives the design method and resistance of concrete components.

The seismic pre-qualification of anchors has been regulated in Europe since the release of ETAG 001 Annex E in early 2013. Anchors subject to this test procedure must then incorporate in the ETA all the required seismic design technical data.

The suitability for seismic loading is classified into two categories:

ETA seismic category C1 – only suitable for non-structural applications according to the EOTA TR045 recommendations.

ETA seismic category C2 – Arduous seismic crack movement tests qualify an anchor as suitable for more demanding structural and non-structural applications.

Our technical webinar will introduce fundamentals of anchor design under seismic condition and how to ensure the proper selection of the qualified anchor and the right design approach considering both categories of ETA seismic loading classification.

The webinar will focus and address the following topics:
