Compliance with current standards and guidelines is essential in construction projects within earthquake-prone areas. Particularly important are the DIN EN 1998-1/NA (Eurocode 8) and DIN 4149. A solid understanding of these standards is crucial to ensure the safety and stability of buildings and to secure property values in the long term. The GFZ's earthquake zone query offers initial information on seismic hazards.
The Importance of DIN EN 1998-1/NA (Eurocode 8)
Transition from DIN 4149:2005-04 to Eurocode 8: Eurocode 8 is progressively replacing DIN 4149. Both standards are based on the core principles of life safety, damage limitation, and functionality. It's important to understand the differences in application and interpretation to appropriately adapt construction projects. DIN EN 1998 uses a probabilistic method based on a recurrence period of 475 years.
Earthquake Zone Maps and Their Limitations
Data Sources and Accuracy: The earthquake zone map is based on geographic coordinates of city centres. It's important to note that the classification is without warranty and independent of the official classifications of the federal states. Always verify the data with official planning maps of the federal states, especially in border regions. The definition of earthquake zones according to DIN EN 1998 differs from the older DIN 4149.
Country-Specific Planning Maps
Importance of the Planning Maps of Baden-Württemberg, Hesse, North Rhine-Westphalia, and Thuringia: The planning maps of these federal states take precedence, especially in border areas and for specific subsoil classes. Consult the official planning maps to obtain a legally binding classification. The planning maps of Thuringia are a vital tool for risk assessment. The earthquake safety with Rigips demonstrates how building materials can contribute to safety.
A comprehensive risk assessment is essential to understand the potential impacts of earthquakes on property values. The CEDIM approach and DIBt data provide valuable tools for quantifying risks and making informed investment decisions. The CEDIM 'Risk Map Germany' focuses on asset assessment to enable consistent risk comparison across various hazards.
CEDIM 'Risk Map Germany'
Asset Estimation for Risk Comparability: The CEDIM project aims to create a unified data base for exposed values (people and real estate). Both top-down and bottom-up methods are used in industrial asset valuation. The spatial distribution of assets within municipalities is taken into account to enable detailed analysis.
DIBt Excel Table
Earthquake zone and subsoil class allocations for federal states: The DIBt Excel table provides a central resource for relevant data on earthquake zone and subsoil class allocation for various federal states. This table is a valuable tool for risk assessment. The table contains information for Bavaria, Hesse, Rhineland-Palatinate, Saxony, and Thuringia.
Methods for Risk Assessment
Probabilistic Seismic Hazard Analysis (PSHA): The PSHA accounts for uncertainties in earthquake frequency and ground motion. This method enables a more accurate assessment of earthquake risk. The PSHA is an important component of a comprehensive risk assessment. The earthquake zone value analysis helps incorporate the results of the risk assessment into the valuation.
When planning and operating geothermal plants, it is important to consider the potential seismic risks. It is crucial to distinguish between natural and induced seismicity and to take appropriate measures to minimise risk. The definition of earthquake zones according to DIN EN 1998 is an important starting point here.
Definition of earthquake zones according to DIN EN 1998
Return period and European Macroseismic Scale (EMS): DIN EN 1998 uses a probabilistic method based on a return period of 475 years. Zones 0-3 correspond to intensities on the European Macroseismic Scale (EMS). Each zone is assigned a designated value of ground acceleration (ag).
Design value of ground acceleration (ag)
Zones 1-3 and their respective ag-values: Zones 1-3 have the following design values of ground acceleration: Zone 1 (0.4 m/s²), Zone 2 (0.6 m/s²), Zone 3 (0.8 m/s²). These values are crucial for calculating seismic equivalent loads. Ground acceleration is an important parameter for the seismic design of structures.
Focus on geothermal plants
Consideration of natural and induced seismicity: In geothermal plants, it is important to distinguish natural seismicity from induced seismicity. Induced seismicity can be triggered by the operation of geothermal plants. Careful planning, construction, and operation are essential to minimise risk. The future of property values also depends on the safe use of geothermal energy.
Building planning and construction in earthquake zones require special care and adherence to specific safety aspects. This applies to both the selection of building materials and the structural design of the building. The earthquake safety with Rigips demonstrates how building materials can contribute to safety.
Building Categories and Consequence Analysis
Importance of Building Categories (I-IV) and Associated Factors (γI): The building categories (I-IV) determine the importance factor (γI) considered in the calculation of seismic response forces. A consequence analysis assesses the impacts of structural failure. Proper assignment of the building category is crucial for safety.
Regularity and Structural Design Principles
Simple load paths, uniform stiffness, ductile design: Regular structural configurations enhance seismic performance. Simple load paths, uniform stiffness, and ductile design are important principles. Minimize setbacks and torsional resistance to increase stability.
Seismic Response Forces
Calculation based on ground acceleration (ag), site factor (S), and importance factor (γI): Seismic response forces are calculated based on ground acceleration (ag), site factor (S), and importance factor (γI). The reference return period is 475 years (10% probability in 50 years). Accurate calculation of seismic response forces is crucial for seismic design. The earthquake zone value analysis helps incorporate these aspects into the evaluation.
