Eurocode 5 provides general rules and rules for buildings that are fundamental to the design of timber structures. Founded on the basis of design given in BS EN 1990, Eurocode 5 is a limit states, partial factor design code. In a limit state design codes, structures are designed for states beyond which the structure no longer fulfils the relevant design criteria.

Key Information

The two different limit states featured in Eurocode 5 – ultimate limit states and serviceability limit states – were defined. Partial safety factors or gamma factors were also outlined.

Key considerations in defining design values of actions were discussed with factors for representative values of actions listed. A simplified set of combination equations were also presented.

Case studies

A new café, designed by Knox Bhavan Architects, stands at the heart of The Level, a well-used and historic park on the main approach to Brighton.

The Enterprise Centre, a new building on the University of East Anglia (UEA) campus is an outstanding example of sustainability and low-embodied carbon construction.
