SCI CONNECT – November 2019

There is pressing demand for improved infrastructure in both developed and developing economies, for example on average vehicles cross structurally deficient bridges more than 188 Million times a day in the US.

Bridge owners and designers in Europe, US and India are becoming increasingly interested in the use of duplex stainless steel for the replacement, strengthening or renovation of bridge structures. SCI is at the heart of developing design rules for stainless steel bridges.

With support from stainless steel producers and manufacturers, Nancy Baddoo chairs the Working Group responsible for the stainless steel Eurocode, EN 1993-1-4. Work is currently underway revising and extending the stainless steel design rules as part of the preparation of the Second Generation Eurocodes, with many improvements which will be relevant to the design of bridge structures.

October saw the opening of the duplex stainless steel two-bridge Garrison Crossing in Toronto - designed using a combination of rules from the Eurocode and the American Institute of Steel Construction (AISC) Design Guide on structural stainless steel, written by SCI.

Francisco Meza and Nancy Baddoo have also been busy drafting the first AISC design specification for stainless steel structures. The rules will be aligned as far as possible with the AISC design rules for carbon steel, modified to suit the distinctive characteristics of stainless steel such as non-linear stress strain characteristics.

Closer to home, the new vehicle crossing at Pooley Bridge in Cumbria will be a stainless steel composite structure spanning 40 m and is due to open next year.

SCI focusses on deconstruction and reuse.

Sustainable construction is currently riding up the agenda. Of the many challenges faced by the steel sector, greenhouse gas emissions and the urgency of addressing climate change, is arguably the biggest. Globally steel production accounts for around 7% of carbon emissions.

Many large steel makers have ambitious plans to develop and introduce new technologies to deliver 'zero carbon steel' but this will take time and a lot of investment and therefore we need to do what we can now to use and reuse steel construction products efficiently.

SCI has always focussed on the efficient use of steel in construction. More recently we have been working on ways to promote the reuse of structural steel and particularly how to design steel structures so that they can be deconstructed and reused in the future.

While we are very conscious of the challenges faced by the supply chain in reusing structural steel, we are also convinced that developing circular economy policy and the need to reduce carbon emissions will mandate reuse in the future. We need to think 'outside the box' and develop new business models to facilitate this.

SCI hosted a one-day event at the Building Centre in London on 8th October to present the findings from two EU-funded projects that are focussed on steel reuse and are nearing completion.

REDUCE, which is co-ordinated by SCI, is focussed on the development of demountable shear connection systems. PROGRESS which focusses on the reuse and design for reuse, of single-storey steel buildings which are seen as the most easy to reuse steel structures.

Speakers from ten research partners across Europe presented the findings from both projects. The presentations freely available on the SCI website.

SCI also launched the new Structural steel reuse protocol (SCI P427) at the event. The protocol, which is underpinned by the work done under the PROGRESS project, gives recommendations on the assessment and testing of sections so that reclaimed structural steelwork can be used with confidence. The Protocol is freely available here.

UK Steel Construction Day 2019 review

This year's event was undoubtedly our most successful yet based on all key criteria. We had the highest attendance (almost 120), the lowest 'no show' rate, an excellent range of interesting and diverse presentations, supportive sponsors and a very 'user friendly' venue

Matthieu Mallié opened proceedings, straight off the Eurostar from Brussels, with an excellent and heavily pictorial presentation about the new bridge in Tintagel. His passion for the design was clear, as was the outstanding achievement of the bridge. We then had a number of presentations that, at one level, could highlight a dichotomy - does creating optimal solutions for a given structure represent the future, or does standardisation represent the future? The reality of course is a combination of the two - for certain building types standard solutions can be optimised and components potentially reused, other types are not suitable for standardisation but offer potentially bigger benefits from optimisation because of their more random nature. The extra steel used in a sub-optimal solution varies by structural form, but Mathew Gilbert showed us that common solutions may use two or three times more than the optimum requires. Accepting that minimum weight does not often represent minimum cost, knowing what could be achieved nevertheless provides a fascinating benchmark.

In parallel with the main session The Steel Piling Group held its flagship event, which was well received with over 40 delegates giving a combined total of 160 for the day. The event titled 'Innovative steel piling solutions' comprised a varied line up of speakers both from academia and industry. Presentations covered developments in the second generation of Eurocode EN 1993-5 (covering steel piling), novel advances in hydraulic piling hammers, and a case study describing sheet pile solutions for the Boston Barrier project.

If you weren't there you definitely missed something!

XII - Conference on Steel and Composite Construction,
in Coimbra, Portugal

The Steel Construction Institute (SCI) attended the XII - Conference on Steel and Composite Construction, in Coimbra, Portugal, organized by the Portuguese Steel and Composite Construction Association (CMM).

The main objective of the conference was to disseminate innovations and new achievements for Steel and Composite Construction. SCI staff contributed to the edition special theme "Steel Structures as the Answer to the Climatic Changes", for which Michael Sansom, Ana Giráo and Ricardo Pimentel made presentations about provisions for greater steel reuse. The SCI is also pleased that their new publication P427 - Structural Steel Reuse is getting noticed by the industry. The keynote speaker and RIBA member Cezary Bednarski described the publication as an important step forward to achieve a more sustainable built environment. SCI staff member Ricardo Pimentel was also awarded with a distinction for one of the best 6 papers in the conference with his paper on "Design for structural stability according to Eurocode 3: fundamentals and practical applications".

J&D Pierce's Training Manager Tom Wallace has been shortlisted as a finalist in the 'Service Leaver of The Year' category in this years' Ex-Forces in Business Awards!

The British Ex-forces in Business Awards is a standout ceremony that commemorates veterans entering the business world and comes to Scotland on 3 December.

There are many social stigmas facing military veterans when they leave service, including unfair assumptions such as they're ill-prepared for 'real-life' and for 'real work' in the private sector. This is one of the few awards ceremonies out there that's doing its bit to dispell these misinformed views. Instead, they're highlighting the skill-sets of ex-military employees, including their applicability to high-level roles in the business world.

The finalists were chosen from a total of 250 nominations by a judging panel of military veterans.

Caunton's apprentices restore a colliery wheel - providing a benefit for the local community

Caunton's apprentices have refurbished an old colliery wheel which, erected by Caunton's erection department, acts as a focal point for activities at a local beauty spot called Colliers Wood.

The background to this goes back a long way. When Caunton Engineering outgrew its Kirkby-in-Ashfield works by the end of the 1980's the company relocated and invested into the Maintenance Workshops of the National Coal Board in Moorgreen in 1990. The Moorgreen Colliery itself had been demolished in 1986 - a colliery that at one time produced one million tonnes of coal per annum. Currently Caunton fabricate and install circa thirty thousand tonnes of structural steelwork from these premises. Over a number of years the shareholders have invested to regenerate the whole former colliery area. Today a new thriving trading estate surrounds the ever-expanding Caunton facilities and the surrounding area has been reconstituted into attractive farmland and countryside. One particular area within this is Colliers Wood. The Friends of Colliers Wood are creating a new activity area within the woodland scene. Part of this area will feature - most appropriately - a colliery wheel which had been rescued from the local Calverton colliery.

The colliery wheel however needed substantial repair and refurbishment, and this was a task attacked enthusiastically and skilfully by Caunton apprentices employed in the company training academy, once used to maintain and repair colliery plant and equipment. The photograph shows work being carried out by two of Caunton's apprentices.
