Overview

prEN 15129-1 - Anti-seismic devices - Part 1: General design rules (CEN draft) sets out the general requirements for the design, manufacture, testing, installation and maintenance of devices intended to modify a structure’s response to seismic action. Intended to supersede EN 15129:2018, this part provides performance-based rules that apply to the full family of anti-seismic devices (fuses, dampers, isolators, sliders, restraints, etc.) and directs readers to Parts 2–6 for device-specific provisions.

Key topics and requirements

• Scope and intent: Defines functional requirements for devices used in seismic and non-seismic design situations and their connections to structural members.
• Performance-based design: Aligns seismic analysis and device verification with the EN 1998 (Eurocode 8) series; requires consideration of design situations, service life, durability and sustainability (EN 1990/EN 1991).
• Reliability and safety objectives:
  • “No failure” requirement for rare seismic events (residual capacity expected, except for fuse-type devices).
  • “Damage limitation” for more frequent seismic actions (limited, repairable damage).
  • Increased system reliability implemented via displacement magnification factor (γ) per EN 1998.
• Limit states:
  • Ultimate Limit State (ULS): verification for Significant Damage and Near Collapse, ductility and residual capacity requirements.
  • Serviceability Limit State (SLS): functional performance for Fully Operational and Damage Limitation states.
• Materials and properties: Materials must conform to European standards; properties must reflect strain, strain rate, environmental effects, ageing and temperature variation.
• Constitutive laws and modelling: Behaviour must be supported by adequate modelling and Type Tests; device properties for analysis come from experimental testing.
• Assessment and AVCP: Performance assessment and verification of constancy of performance (AVCP) required for device components.
• Documentation, installation and maintenance: Manufacturers must supply test reports, installation guidance, inspection/maintenance and replacement procedures; devices must be accessible for inspection and serviceable during structure life.

Applications and users

• Structural and geotechnical engineers specifying seismic mitigation systems
• Manufacturers and designers of seismic isolators, viscous/visco‑elastic dampers, sliders, fuse restraints
• Certification bodies, testing laboratories and notified bodies (AVCP)
• Contractors, installers and facilities managers responsible for inspection, replacement and maintenance
• Asset owners and infrastructure operators seeking compliance with Eurocodes and European standards

Related standards

• EN 1990, EN 1991, EN 1998 (Eurocodes) - design principles and seismic actions
• EN 1337 series - structural bearings and slider definitions
• prEN 15129 Parts 2–6 - device-specific requirements (Rigid Connection Devices; Displacement/Velocity Dependent Devices; Elastomeric Isolators; Curved & Flat Surface Sliders)

Keywords: anti-seismic devices, seismic isolators, seismic design, EN 15129-1, Eurocode, CEN, viscous dampers, lead rubber bearing, seismic protection.
