Eurocode Basis of Structural Design
The Eurocode: Basis of Structural Design (known informally as Eurocode 0 and abbreviated as EN 1990) is a foundational document within the series of European standards that guide structural design across Europe. These standards, collectively referred to as Eurocodes, provide a comprehensive framework for the engineering and construction of buildings and other civil engineering works.
EN 1990 sets out the principles and requirements for safety, serviceability, and durability of structures. It establishes the basis for their design and verification and is intended to be used in conjunction with the other Eurocodes, such as:
- EN 1991: Eurocode 1 - Actions on Structures
- EN 1992: Eurocode 2 - Design of Concrete Structures
- EN 1993: Eurocode 3 - Design of Steel Structures
- EN 1994: Eurocode 4 - Design of Composite Steel and Concrete Structures
- EN 1995: Eurocode 5 - Design of Timber Structures
- EN 1996: Eurocode 6 - Design of Masonry Structures
- EN 1999: Eurocode 9 - Design of Aluminium Structures
Principles and Requirements
EN 1990 outlines general principles for the design of structures to ensure they are sufficiently robust and resilient to withstand various actions such as loads, environmental influences, and accidental impacts. The document defines the basis for the design of structures by establishing:
- Reliability: Ensuring that structures perform as intended over their operational lifetime.
- Durability: Guaranteeing a long-lasting performance despite environmental conditions.
- Serviceability: Ensuring comfort and usability without compromising stability.
Design Philosophy
The Eurocode encourages a performance-based approach to structural design. This means that while it provides specific guidelines and standards, it allows for flexibility and innovation in how these standards are achieved. The aim is to harmonize the safety and quality of structural engineering across Europe while allowing individual engineers and architects the freedom to design creatively within those parameters.
Integration with Other Standards
EN 1990 is meant to be used in combination with other Eurocodes to ensure a comprehensive approach to structural design. Each specific Eurocode focuses on different types of structures or materials, such as concrete, steel, or timber, and together they form a cohesive framework for all types of construction.
