SCI CONNECT – July 2019

Sometimes it feels like 'innovation' is the most overused word in the English language, 'literally'! To progress, society just needs changes that bring improvement and it doesn't matter if they are quite subtle and evolutionary, rather than revolutionary. So for our 2019 UK Steel Construction Day we will be showcasing a number of projects, ideas and processes that drive towards improved steel construction in very different ways.

The Government is investing heavily in Transforming Construction, with the now familiar stated aims to provide better quality construction at reduced cost more quickly and with a preference for offsite solutions (partly to combat future labour shortages). The work on 'platforms' being undertaken by Bryden Wood has been widely recognised and we are delighted that Kevin Masters will update us on the work they are doing to help bridge the gap between construction and manufacturing. With related aims we have been fortunate to secure funding from Innovate UK for a BCSA led project looking at offsite integrated modules. The outcome of this project will be generic design and client guidance, aimed at achieving transformation of a significant proportion of everyday steel buildings. The event will be timely for us to present outcomes as this project will be drawing near to a close in November.

It is clear that to achieve real improvement new technical solutions alone will not to be sufficient. Client buy-in and willingness to try something different is also going to be needed. Pete Winslow from Expedition, currently seconded to WSP, will tell us how significant savings, in material and overall cost, can be made if a client is willing to spend a little more on design. His example concerns a roof of complex form and the benefits of wind tunnel testing to determine design loads more accurately.

Significant improvements in sector performance will only ever be achieved by solutions that have widespread application. But we should always leave room for iconic one-offs to stir our emotions. One such highly publicised project is the new bridge at Tingtagel, which we will hear about from Matthieu Mallié of Ney and Partners. The bridge includes some interesting choices of steel driven by demanding design requirements.

Other speakers remain to be confirmed.

Design of steel concrete composite (SC) Structures (P414)

SCI has just published a new design guide entitled Design of steel concrete composite (SC) structures (SCI-P414). It provides recommendations for the design of panels comprising two steel plates connected by a grid of tie bars with structural concrete between the plates, typically used for walls. It also covers panels comprising a steel plate stiffened by T-section ribs welded to the plate (referred to as half-SC), typically used for floors. The plates act as load bearing formwork during placement of the concrete, thereby eliminating the need for temporary formwork. In the permanent condition, the plates act as reinforcement to the concrete. In SC panels, the tie bars hold the two plates together at the construction stage and provide transverse shear reinforcement in the permanent condition. Composite action between the steel plates and the concrete is achieved through the use of headed shear studs welded to the steel plates.

The guide covers material grade selection, calculation of element and connection resistance, calculation of thermal effects and resistance at elevated temperature. The guide also covers the calculation of actions at the construction stage and verification of the resistance under those actions.

The work was undertaken within a project funded by the European Union's Research Fund for Coal and Steel (grant agreement RFSR-CT-2013-00017) and EDF.

Reuse of steel structures and the circular economy

SCI continues to research how to reuse structural steel effectively and we are hosting a free event at the Building Centre in London on 8th October to disseminate our findings. Come and learn from SCI and our European partners including VTT, Delft University of Technology, the University of Luxembourg and RWTH Aachen University and give us your feedback. Presentations will cover testing of new demountable systems, practical design guidance and the environmental and economic benefits of deconstruction and reuse. You can book on-line here.

As a reminder, we are also developing a protocol for reusing structural steel and we would welcome any comments on this. You can find a draft of the protocol here.

Please send any comments to m.sansom@steel-sci.com before the closing date of 31st August.

Eurocode training in Kenya - postscript

After ten days of training in Kenya on steel design to the Eurocodes, two issues stand out: firstly, (and not surprisingly) concrete is the material of choice, and secondly that a key feature of the Eurocode suite is consistency between the Standards. Design to EN 1993 demands steel manufactured to a referenced material Standard and anticipates that the fabrication and erection will be executed to EN 1090.

These are simple principles that generally pass unnoticed in European countries, but in other parts of the world have important implications when developing National Annexes. If steel is not to a Standard there will be an immediate effect on the material factors, but there may also be more subtle impacts, for example on the ductility of the material which is presumed in many resistance checks. Execution to EN 1090 requires - for example - the careful contribution of a Responsible Welding Coordinator, but if appropriately qualified and experienced personnel are simply not available, a different approach for weld design may be needed. Material, design and execution must be mutually consistent.

These are very real issues to be considered in non-European countries, in addition to the obvious differences of wind actions and snow loads, so the challenge of adopting Eurocodes is not straightforward. Of note is that there are even more questions surrounding the use of concrete - the base materials, mix proportions and quality control throughout the concreting process - are all areas which may have an impact on the design assumptions.

WSP young engineers welcomed to Caunton

Caunton were delighted to welcome a team of 15 young engineers from the renowned consulting engineering practice WSP recently. The engineers spent the day learning how a structural steelwork contractor operates. There were works tours of Caunton's three main manufacturing operations - preparation, production and painting. There was a presentation by Managing Director, Matthew Shimwell, featuring among other things the interface between the engineer and the steelwork contractor, and how they can understand and help each other. The afternoon was occupied by the opportunity to learn the practical skills of welding using equipment supplied on site in the accredited Caunton Training Academy, under the watchful eye of the Academy supervisor. The photograph shows the young engineers prepared for action.

Competition was introduced to this exercise with a contest to see who learnt the quickest and welded the best. The photograph shows the two winners with their trophies, flanked by Matthew Shimwell (on left) and WSP's group leader Andy Heffer.

WSP engineered The Shard, London's (and Europe's) tallest building. They are currently engineering London's second tallest building 22 Bishopsgate. Both steel framed. Caunton are pleased to be helping these WSP engineers learn more about steel and how it can be used practically.

Steel Frame Stability Course
Wednesday 18 September 2019 - Bristol

Frame stability concerns the significance of second-order effects and is highlighted as an essential check for all frames in BS 5950 and EC3.

Whilst in many braced frames the effects will not be significant, designers should be confident in using the simple checks to determine frame sensitivity, and the simple rules to allow for such effects.

The course provides guidance on:

  • Braced frames
  • Continuous frames
  • Portal frames

Having attended this course you will;

  • Be able to check any frame for second-order effects
  • Appreciate the scope of the provisions in the design standards
