EN 1998-2-3 Seismic Design of Bridges and Viaducts
The European Standard EN 1998-2:2015 + A1:2017, "Structures - Structural use of soils - Part 2: Geotechnical design," specifically addresses the geotechnical aspects for seismic design, particularly relevant to bridges and viaducts. This service focuses on compliance with EN 1998-2-3, which deals explicitly with the seismic design of bridges and viaducts.
The standard is critical in regions prone to earthquakes, ensuring that structures are resilient enough to withstand or recover from significant shaking events. The design must account for potential ground motion, which can vary widely depending on location, soil type, and other environmental factors. This service provides comprehensive testing, analysis, and certification to ensure compliance with the European standard.
The primary goal of seismic design is to protect lives by ensuring that bridges and viaducts do not collapse or fail during an earthquake. It also aims to minimize damage to structures, thereby reducing repair costs and downtime. The standard integrates various aspects such as soil dynamics, structural response, and lateral force effects. Compliance with this standard ensures that the bridge or viaduct can perform optimally under seismic loading.
The testing process involves multiple stages, from preliminary design through detailed analysis and final certification. This includes:
- Review of existing structures for potential vulnerabilities
- Evaluation of soil conditions using advanced geotechnical tests
- Structural modeling to simulate earthquake forces
- Data collection during real-world events where available
- Certification and issuance of reports
The service focuses on providing detailed analysis and certification for compliance with EN 1998-2-3. This involves:
- Geotechnical investigations to determine soil properties
- Structural assessments using finite element modeling (FEM)
- Evaluation of dynamic response under seismic loading
- Testing for lateral force resistance
- Comprehensive reporting and certification
The standard emphasizes the importance of accurate data collection, which is crucial for effective design. It also highlights the need for continuous improvement in testing methodologies to ensure robustness against future seismic events.
A key aspect of this service is the use of advanced instrumentation during tests. This includes accelerometers, strain gauges, and displacement sensors to measure structural response accurately. The data collected is used to refine models and improve design practices over time.
The testing process for compliance with EN 1998-2-3 typically involves:
- Initial site investigation to assess soil conditions
- Geotechnical testing using penetrometers and other tools
- Structural modeling with finite element analysis (FEA)
- Simulation of seismic events through shake table tests or computer simulations
- Evaluation of test results against the standard's criteria
- Certification and issuance of compliance reports
