What is BS EN 1993-1-2:2018?

BS EN 1993-1-2:2018, also known as Eurocode 3-Part 1-2, is a European standard that provides rules and guidelines for the structural design of steel structures subjected to fire. It was developed by the European Committee for Standardization (CEN) and is widely accepted across Europe.

Key Requirements of BS EN 1993-1-2:2018

One of the main objectives of BS EN 1993-1-2:2018 is to ensure the safety of steel structures in case of fire. The standard covers various aspects, including:

Fire resistance requirements: It provides the necessary calculations and tests to determine the fire resistance of different steel components used in buildings and other structures.

Design methods: The standard presents detailed design methods for structural elements under fire conditions, considering factors such as temperature distribution, material properties at elevated temperatures, and load-bearing capacity.

Protection measures: BS EN 1993-1-2:2018 suggests different protective measures, such as intumescent coatings and fireproofing materials, to enhance the fire resistance of steel structures.

Structural analysis: The standard outlines the procedures and methods to perform structural analyses during fire events, considering factors like thermal expansion, strength reduction, and structural stability.

Benefits and Significance

The implementation of BS EN 1993-1-2:2018 brings several benefits and significance to the field of structural engineering:

Improved safety: By following the guidelines provided by the standard, engineers can ensure that steel structures maintain their integrity and load-bearing capacity during fire emergencies, minimizing the risk to human life and property.

Uniformity and compatibility: BS EN 1993-1-2:2018 harmonizes the design approaches used across different European countries, ensuring compatibility and facilitating the exchange of structural expertise and resources.

Efficient use of materials: The standard allows for more efficient and optimal use of steel materials in construction projects, reducing costs and promoting sustainability by avoiding material waste.

Enhanced international collaboration: European countries using BS EN 1993-1-2:2018 can collaborate more effectively on cross-border construction projects, as they follow the same set of rules and guidelines.


BS EN 1993-1-2:2018 is a crucial standard that ensures the safe design and performance of steel structures under fire conditions. Its implementation offers improved safety, uniformity, efficient material usage, and enhanced international collaboration. By adhering to this standard, engineers can confidently design steel structures that withstand the destructive forces of fire while protecting lives and valuable assets.
