PUREST (Promotion of new Eurocode rules for structural stainless steel) is a collaborative European project which is developing a comprehensive package of design guidance and tools to disseminate recently developed information and knowledge on structural stainless steel. Stainless steel is used for a wide range of structural applications in aggressive environments where reliable performance over long periods is required.

With partners from Germany, France, Belgium, Sweden, Finland, Czech Republic, Spain, Portugal, Italy and Poland, SCI has prepared the Fourth Edition of the Design Manual for Structural Stainless Steel, which consists of design recommendations, 15 design examples and a full commentary giving the basis for the design rules. The Fourth Edition aligns with the 2015 amendment to the stainless Eurocode, EN 1993-1-4, and also gives new data on fire, durability, ferritic stainless steels, and new design methods which take advantage of the increased strength arising from the work-hardening characteristics of stainless steel.

The Design Manual is now being translated into 9 European languages. The existing suite of carbon steel Eurocode 3 design applications developed by the ECCS is being extended to cover stainless steel also. A library of standard section sizes has been compiled and design software in accordance with EN 1993-1-4 for PCs and iOS/Android mobile devices is under development.

National seminars in 11 European cities will be held in the autumn to launch the Design Manual, starting on 26 September with the UK seminar in London. Further deliverables include recorded webinars for use in ‘lunch and learns’ and a package of teaching resources for engineering students. All the PUREST resources will be available for free download by the end of 2017 at

European Commission recommend SCIENCE as showcase success story

SCI together with UK and European partners have completed a four year European funded project SC for Industrial, Energy and Nuclear Construction Efficiency (SCIENCE) investigating the behaviour of SC structures.

SC is the name of a generic steel-concrete composite construction system using planar components comprising two steel plates connected by a grid of tie bars with structural concrete between the plates. The plates act as load bearing formwork during the placement of the concrete (core) and, in the completed condition, they provide the reinforcement to the concrete. The tie bars, apart from holding the two plates together during transportation, erection and concreting, act as transverse shear reinforcement. Composite action between the steel plates and the concrete core is achieved through the use of headed shear studs welded to the steel plates.

Several manufacturers of third generation nuclear reactors have made composite steel-concrete (SC) modular construction an integral part of new nuclear power plant (NPP). Modularization using SC structural elements speeds up construction, simplifies the attachment of equipment support points and reduces costs. However, whist design codes were developed in Japan, South Korea and more recently the USA, there has been no European guidance for the design of SC structures.

The final project report was presented to the European Commission’s Expert Monitoring Group (TGS8) and was recommended for showcasing as a success story.

An innovative form of Steel-Concrete (SC) Structures for Nuclear Power plants

New generation NPP manufacturers have been developing modular construction techniques that make greater use of pre-fabrication and factory assembly and reduce reliance on site activity. Most have adopted a technique that uses composite steel/concrete (SC) modules made by pouring concrete between two steel plates. The plates serve the dual purpose of reinforcement and permanent formwork to the concrete. Shear studs welded to the inside surfaces of the plates ensure composite action between the steel and concrete and can be spaced such that the compression steel plates do not buckle under load. They also provide the means for easy attachment of support points for equipment, eliminating the need for embedded steel plates or concrete expansion anchors.

To support the surface plates during assembly, lifting, transportation, concrete pouring and curing, the two plates must be connected together to form a self-supporting unit. In this way, parts of modules may be fabricated off-site and transported as units to be assembled on-site and connected together. Many attempts have been made over the past 25 years to devise practical, economic and safe methods of connecting the plates. SCI has been working with SCI Member Caunton Engineering in a project funded by Innovate UK to design and construct a new generation of SC modular construction (‘Steel Bricks’) that overcomes the manufacturing problems of earlier SC systems. A Steel Brick is made by cutting a pattern into a flat steel plate and then folding the plate to form an ‘L’ shape. Shear studs are welded to the sides of the ‘L’ section and then two ‘L’ shaped plates are welded to form a ‘U’ shape. The circular holes in the base of the ‘U’ allow concrete to flow between bricks joined side-by-side and Steel Bricks can be welded together to create large structural modules. The base of the ‘U’, which is integral to the Steel Brick, provides the means of holding the two sides of the panel together and acts as out-of-plane shear reinforcement to the concrete.

Following completion of several workshop and field trials, a full scale structure (part of a diesel generator building on a nuclear power plant site) has been constructed to demonstrate the buildability of the system.

A full paper demonstrating the research findings is available at ICE as part of their ICE Proceedings.

Designing in stainless steel

Tuesday 26 September 2017, Imperial College London

This one day seminar will launch the Fourth Edition of the Design Manual for Structural Stainless Steel and will equip engineers with the skills necessary to design structural stainless steel in accordance with current European design practice, the seminar will demonstrate design versatility and highlighting procurement issues. Each delegate will receive a copy of this new publication.

The seminar is part of PUREST (Promotion of new Eurocode rules for structural stainless steel), a European dissemination project funded by the Research Fund for Coal and Steel.

Cost to attend £50, refreshments included.

SAVE the Date – SCI Annual Event

Steel Construction 2030 – Opportunities and needs

Tuesday 14 November, Royal College of Physicians, London

Despite much overuse of the word ‘innovative’, the construction sector has always been relatively conservative. Speakers from both SCI and our member companies will look at some of the developments that could become of growing relevance over the coming decade, including new forms of construction, solutions to minimise the use of new materials and maximise the benefits offered by steel, and the appearance of a second generation of Eurocodes. Drivers will change and push steel construction in these directions, but how long will it take?

A cycling theme among SCI staff

In the baking heat over the 17-18 June weekend, SCI staff were out on their bikes. Mark Allen completed the London-Brighton race to raise money for The British Heart Foundation. Graham Couchman was riding thirty-five-year-old vintage steel in the Peak District. We hope they enjoyed their days and survived them well.
