Eurocode 8 and its implications for UK-based structural engineers


Eurocode 8 ( EN1998: Design of structures for earthquake resistance ) is in six parts and covers all aspects of seismic design for a wide range of both material types and structures. It includes geotechnical aspects, but excludes special structures. It is based on justified models, rather than an empirical approach, and it  is suggested that structural engineers with no background in seismic engineering should obtain specialist assistance. The seismic hazard is expressed by a single parameter, the peak ( zero period ) at the surface on rock for a reference mean return period ( 475 years recommended ). The geotechnical issues are fully covered, including: soil properties, site characteristics, foundation design, interaction between soil and structure, and earth retaining structures. The design of buildings is discussed, including material specific rules. Existing buildings, bridges and other structural types are also addressed. The code provides simplified design methods for areas of low seismic activity, such as the UK. It is anticipated that because of the low risk, the code may not be applied in the UK except to the design of high risk installations. 31 refs.
