The consideration of seismic risks in the design of structures was once limited to the nuclear industry. Today, a large part of structures are covered by seismic regulations.
Seismic phenomena are known to engineers. However, carrying out studies remains delicate. And this because of the methods used and the regulations in force.
This complexity is sometimes the cause of more or less important approximations.
These can lead to inadequate designs, increased construction or repair costs, or even to hasty conclusions that condemn a building to destruction and reconstruction.
Our experts are regularly solicited to respond to seismic problems. They respond to your needs by proposing a complete and adapted approach, whatever the type of structure.
This may include several services:
We can help you at different levels.
At Sixense necs, 80% of our missions are related to seismic issues.
Our 800 seismic references accumulated in 20 years of existence are the result of the know-how of our experts, their knowledge of regulations, their mastery of adapted software and the recognition of their peers.
Our qualified opinions : They are relevant and detailed and should be dissociated from a simple statement of regulatory deviation. It is not because the structure does not comply with the regulatory provisions that it does not resist an earthquake.
Our experts are recognized by their peers in the scientific community and industry. They master both structural and material aspects.
Our mastery of the associated subjects : modeling of materials and structures (CM, BA, wood, masonry, composite structures), soil-structure interaction, dynamic soil impedance, seismic hazard (spectrum, generation and deconvolution of accelerograms)
Our pedagogy: we take the time to explain the results of a diagnosis and the proposed seismic reinforcement solution, in particular through digital illustration tools: Building Information Modeling, 3D modeling, videos.
Our engineers : are specialized in repair, reinforcement, design or optimization solutions.
Our calculation software : are recognized for their richness and degree and validity.
Code_Aster : structural calculation platform developed by EDF to control the safety of nuclear facilities.
Miss3D : software for calculating the dynamic response of soil (impedance and soil-structure interaction), developed by the École Centrale Paris.
