MINIMIZE DAMAGE, MAXIMIZE SAFETY
Design your fastenings to resist seismic forces
Structures designed for seismic scenarios to the state-of-the-art standards ensure a high degree of structural integrity & occupant safety.
With earthquakes placing huge demands on the resistance & connections of a building’s structural & non-structural elements, appropriately designed fastenings using post-installed anchors must ensure robust performance that do not compromise both structural integrity or occupant safety.
UPCOMING WEBINARS ON SEISMIC
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.

How anchors behave in an earthquake
Seismic conditions significantly change the behavior of anchors, compared to static conditions.
How Hilti anchors comply with seismic codes
According to the state-of-the-art EN 1992 (Part 4):2018, designing fastenings to resist seismic actions requires use of anchors qualified to categories C1 & C2.
Hilti produces a wide range of anchors qualified to the latest European Assessment Documents (EADs) for both C1 & C2 categories, enabling the designer to undertake a compliant design.
RELEVANCE IN India
The earthquake hazard map in IS 1893 Part(1):2016 shows the acceleration coefficient for different locations across India.
Seismic Design is relevant in the large part of the country, represented on the map.
SEISMIC PERFORMANCE RELEVANCE TO ANCHOR CONNECTIONS
In India, seismic category C2 is required in most cases for structural elements due to the ground acceleration zones mentioned earlier. Seismic category C2 is also required for non-structural elements in buildings with high importance and high ground acceleration zones.
Whereas for buildings with a low importance class in low ground acceleration zones seismic category C1 shall be considered.

HOW DO I DESIGN ANCHORS FOR SEISMIC AREAS
At Hilti, our engineering team can help you design anchor systems for all types of load conditions including seismic. Just contact your local office for more details or you can use Hilti PROFIS Engineering software. This includes code compliant Hilti products with relevant documentation and specifications.
Hilti PROFIS Engineering software performs seismic calculations according to EN 1992 (Part-4):2018. This gives three solutions for anchoring base plates in seismic areas:
Capacity design - 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.
Elastic design - 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 to ensure that the cause of failure is steel failure.
We’ve also added our own Hilti research results into PROFIS Engineering software, so that you can find solutions, which go beyond EN 1992 (Part-4):2018.
