One of the greatest benefits of steel structures, lightness, has a disadvantage; potential vulnerability to dynamic problems. After construction, it is hard to make adjustments, since only major changes to stiffness, mass and damping can make a significant difference to the response. It is therefore important to design floors for vibration, as in some cases it can be the most onerous criterion when sizing the structural elements.
SCI publication P354 provides a simplified procedure to calculate the response of a floor due to footfall excitation for framing arrangements generally regular in plan. As with every simplified approach to a complex phenomenon, some of the generalising assumptions make the result conservative. Finite Element Analysis provides a means for overcoming this conservatism, but can present significant challenges to inexperienced practitioners.
The SCI has a service to assist engineers with determining a suitable design for floors against vibration. We have recently developed the capability to import BIM models directly into our software, increasing accuracy and reducing cost. After analysis a report of the findings is provided, with suggestions on how to improve the behaviour if required.
In most cases the analysis costs £4000 per floor, no matter the complexity of the structural arrangement. There may be additional fees if extra processing is required.

RFCS Projects
BATIMASS
SCI is finalising an RFCS project, with partners from Germany, Finland, Spain and Oxford Brookes University, looking into how the thermal capacity of relatively lightweight steel buildings can be enhanced. Areas of work that have been explored in the project, include dynamic thermal modelling of buildings in particular investigating the impact of exposed composite floor decks; water-cooling of floor slabs and the use of phase change materials (PCM) in composite floors, suspended ceilings and within PCM batteries. Testing work will be completed in the next few months and the final report submitted in early 2016. For more details contact Michael Sansom.
TABASCO
The quality of the outcomes from TABASCO, a European funded research project coordinated by SCI between 2011 and 2014 and involving four other partners from France, Germany, Finland and the UK, was recently praised as “remarkable” by the European Commission’s relevant technical committee. The project investigated how thermal bridging in steel construction can be minimised to improve building energy performance. It resulted in the development of an atlas of construction details for residential, commercial and industrial buildings as well as a series of best practice design guides, with a view to assist architects and suppliers in achieving energy efficient steel construction. The work carried out over the 3 year long project involved nearly 1,000 thermal simulations, laboratory tests, onsite surveys as well as structural testing of innovative solutions.
For more details contact Guillaume Vannier.
NEW PROPOSALS
September saw SCI submit a number of new proposals to the research Fund for Coal and Steel. This has proven to be a valuable source of research funding for many years, and is key to SCI remaining at the leading edge of steel construction. Diverse topics covered include; execution standards for light steel, demountable steel construction, Eurocode rules for stainless steel, higher strength steels, and composite joints. The outcome of the assessment process should be known in early 2016. |

Norwegian Steel Construction Association
On 10th September Graham Couchman gave a presentation on composite construction as used in the UK to a delegation brought over to London by the Norwegian Steel Construction Association. As part of their mission to learn more about UK practice, the event included fascinating presentations on The Shard and the Leadenhall building from SCI members WSP and Arup respectively. Graham was pleased to receive a traditional Norwegian cheese cutter as a sign of gratitude for his input. |

SCI Annual Event 2015
12 November 2015, The Crystal, Royal Victoria Dock, London
The past, present and future of steel construction
To coincide with SCI’s 30th birthday we will be reflecting on the past, and looking at predictions for the future, to provide an insight into the shape of steel construction in years to come. We have witnessed some massive changes in the UK, not least of which is ever growing competition from outside these shores. However, we can also benefit from an international perspective to see how other markets have evolved their steel production, steel products and site practices to suite changing commercial, technical and societal drivers.
You will hear from:
-
Mike Walsh of Hatch Consulting who will illustrate how history tells us that the future for steel is bright. He will discuss how the technologies of steel production have evolved and what the limitations for steel products are. Generation of revenue from producing steel, not by selling tonnage, but from differentiation and the provision of good service will also be considered.
-
Carl Perry of BlueScope will take a global perspective to consider how products and construction processes change to suit different economic and technical drivers. He will highlight the trend to use less, but higher strength, steel and the other materials it must compete with. By considering different markets we can see how UK products and practice may evolve.
- Graham Couchman of SCI will reflect on the rapid rise to dominance of steel construction in the UK since the decision to form an independent organisation (SCI) to develop and promote the proper and effective use of steel as a constructional material. He will highlight some landmark projects and achievements for the sector, and consider how the nature of SCI has evolved over the years.
