SCI CONNECT – May 2019

Growing realisation of the urgent need to reduce or even eliminate, greenhouse gas emissions is focussing attention on what we build and what construction materials we use. Although the focus has been on reducing operational impacts from heating, cooling, lighting, etc. there is growing pressure to think more about the impacts of construction materials, so-called embodied impacts.

Steel manufacture is energy and carbon intensive and it is recognised that the sector is difficult to decarbonise; globally steel making accounts for around 8% of global greenhouse gas emissions and around 50% of all steel goes into construction. The steel industry has made good progress in reducing its emissions but efficiency is approaching the theoretical limit using existing technologies. Although some steel-makers are exploring exciting, new step-change technologies, easier, lower cost reductions can be made from demand-side measures particularly from using steel products more efficiently; this includes reusing as opposed to the current practice of recycling by remelting, structural steel.

Building on recent national and international projects on structural steel reuse, SCI is developing a protocol to help facilitate the reuse of structural steel sections reclaimed from existing building structures.

The protocol proposes a system of investigation and testing to establish material characteristics, with advice for designers completing member verifications. The protocol places important responsibilities on the holder of salvaged steelwork including identification, assessment, control procedures and declarations of conformity.

The protocol is founded on the principle that given appropriate determination of material characteristics and tolerances, (re)fabricated salvaged steelwork may be fabricated and CE marked in accordance with BS EN 1090.

The draft protocol is available here and we very much welcome comments and feedback from all interested parties.

The intention is to consult on the draft protocol over the summer and then formally launch it at an SCI-hosted event at the Building Centre in London on 8th October - click here for further details.

New Durability of Steel Piling Guidance

The Steel Piling Group has recently updated its popular guide to the durability of steel piles. The Guide published by the Steel Construction Institute (SCI) is an in depth guide providing industry with an overview of the corrosion process, it outlines the corrosion performance of steel piling in various environments, and reviews the protective measures that can be taken to increase the life of steel piles where necessary.

Steel piles can offer a sustainable and economic solution to a wide range of geotechnical and foundation challenges, whether acting as bearing piles, retaining walls, cofferdams or cut-offs. Among the aims of The Steel Piling Group are to identify, encourage and publish research to advance the use of steel piling systems and to provide a cross industry source of knowledge of design and construction aspects of steel piling. This guide is a key element of that work; bringing together experts from across industry. It includes discussion on the process of corrosion in various piling environments; presents long term monitoring and test results from ArcelorMittal, British Steel and Highways England both in Europe and further afield, and describes how to account for durability within design (in accordance with Eurocode) and how durability may be extended by various techniques including use of low corrosion steels such as AMLoCor™.

The guide has already been received well by industry and is referenced by other standards and specifications such as ICE SPERW. It complements EN1993-5 for the design of steel piles and presents a worked example of steel sheet pile design to illustrate the approach to designing for durability.

The guide is free of charge and can be downloaded here

Progress Project - wins 1st Prize in the Innovative project or service category

On the 15th May, the Progress Project was awarded 1st Prize beating 23 finalists in the innovation category at the Barcelona Building Construmat. Congratulations to all those involved in the Project. SCI is a Partner in the EU project (PROGRESS). The focus of PROGRESS is the deconstruction and reuse of elements of single-storey steel buildings. The project addresses both the structural and envelope elements and their interfaces and also considers both the reuse of existing buildings and how new single-storey buildings can be designed and constructed to facilitate future reuse. Read more information on the Progress project.

UK Steel Construction Day, Thurs 7th November 2019, 1 Birdcage Walk, London

This year the main theme of UK Steel Construction Day is 'Innovative steel solutions'. We will look at a range of different solutions that address the multiple needs to build with improved speed, quality, safety, predictability, and using less materials. Some of these solutions are already being applied, others are for the future. Speakers from both SCI and industry will present how innovative designs and products can provide the industry with economical and energy saving solutions. A second focus will be the related world of product certification, and what SCI and its clients are doing to help ensure products are correctly specified, constructed and used.

New Guidance

FIS & SCI launch new edition of Design and Installation of Light Steel External Wall Systems (Technical Report ED017)

This new guide, launched on 16 May 2019 will provide best practice, educate clients and installers, and avoid issues caused by last minute changes. The guide is for anyone who designs and installs SFS infill walls, and anyone checking that the products are being correctly installed, such as a 'Clerk of Works.' It will help to raise standards and show clients what SFS is and how it works. The guidance includes practical check lists for all parties included in the process; designers, specifiers, suppliers, installers and main contractors.

This guidance is freely available to download from both;

SCI Advisory Questions and Answers

For SCI Sole Trader and Corporate members, SCI offers support through our Advisory Service. If you require code clarification or have any question please ask the SCI Advisory team.

The question below is typical of that asked of our Advisory Team;

Question: Section 7.4.2 of the Design manual for structural stainless steel says a fillet weld should not be used where a bending moment about the longitudinal axis of the weld causes tension in the weld root. Does this not occur where a fillet weld is provided on both sides of a plate?

Answer: Strictly this is so but the restriction is intended to apply to a one-sided fillet weld where the bending moment could cause the unwelded part of the joint to open and extend through the root of the weld. It applies equally to welds in stainless and carbon steel.

If you are an SCI member please see the answer to all Advisory questions on the SCI Information Portal.

Design of steel portal frame buildings to Eurocode 3 (P399)

Design of steel portal frame buildings to Eurocode 3 (P399) This publication deals with portal frames with more than one bay, 'hit and miss' frames, plastic analysis and design as well as elastic. It deals with issues which are not covered by BS EN 1993-1-1 on elastic checks on haunches and gives guidance of initial imperfections based on research carried out over the last two years.

Design of Composite Beams using precast concrete Slabs in accordance with EC4 (P401)

Design of Composite Beams using precast concrete Slabs in accordance with EC4 (P401) The guidance discusses the particular issues affecting the use of precast concrete concerning the requirements of effective shear connection and transverse reinforcement. Reference is made to small scale push out tests, and earlier composite beam tests, that have established reduction factors for the design resistance of welded shear connectors as a function of the gap between the ends of the precast concrete units, and the amount of transverse reinforcement provided.

Thermal bridging in steel construction (P410) Thermal bridging in steel construction (P410)

Thermal bridging in steel construction (P410) This publication provides an introduction to thermal bridging, an explanation of the consequences of thermal bridging and describes how these effects are considered and quantified in the UK Building Regulations. Different methods for minimising thermal bridges in hot-rolled structural steel frames are described and examples are used to demonstrate the different methods.
