Earthquakes are much more common than we realise. They happen every day all over the world.
Not only do they cause loss of life and serious injury, but they can also do great damage to buildings and the economy.
All this can be limited by good seismic construction design and specification.
It’s important to include seismic design for both non-structural and structural elements of a build, as research shows that non-structural systems suffer the largest damage in commercial buildings during an earthquake.
Seismic conditions significantly change the behaviour of anchors, compared to static conditions.
There are already codes in place to determine which anchors should be used in seismic areas.
EOTA TR045 clearly states most of the applications only allow the use of category C2 anchor systems for seismic areas.
At Hilti we produce a range of anchors, which are code compliant and fit seismic performance category C2.
At Hilti our engineering team can help you design your anchor systems – just contact your local office for more details.
Or, you can use our Hilti PROFIS Anchor design software. This includes code compliant Hilti products in 2D and 3D with relevant documentation and specifications.
Our PROFIS Anchor software performs seismic calculations according to EOTA TR 045. This gives three solutions for anchoring base plates in seismic areas:
The anchorage is designed for the force corresponding to the yield of a ductile component, or if lower, the maximum force that can be transferred by the fixture or the attached element.
The fastening is designed for the maximum load assuming an elastic behaviour of the fastening and of the structure.
Design with requirements for anchor ductility
This design for ductile steel failure requires an anchor classified as ductile. This approach is also applicable only for the tension component and some provisions need to be observed in order to ensure that the cause of failure is steel failure.
We’ve also added our own Hilti research results into PROFIS Anchor design software, so that you can find solutions, which go beyond EOTA TR 045.
