In 2015, SCI embarked on a 3-year EU funded research project entitled 'Steel Hybrid Onshore Towers Installed with Minimal Effort (SHOWTIME)' with seven other European partners. The objective of the project was to develop an alternative design for tall onshore wind turbine towers consisting of a lattice structure for the lower section of the tower and a tubular upper section. The project is now coming to an end and its results will be disseminated during a full-day Seminar on 28th June 2018 in London.

The SHOWTIME project comprised 5 technical work packages, starting with a parametric study assessing various tower configurations (with different hub heights, proportions of lattice/tubular sections, height/spread ratios and number of legs) to optimise the design of the hybrid lattice-tubular tower. Detailed design of a number of 185 m high wind tower configurations consisting of a 120 m lattice section and a 65 m tubular section was then carried out. Designs were developed for the transition component between the lattice and tubular sections of the tower, including the integration of the lifting system for the erection of the tubular section. The erection process was investigated in detail during the project, and feasibility studies were conducted using scaled prototypes. In addition, new steel grades with increased material properties for wind fasteners were tested against ISO 898 requirements. An essential part of the project was to assess the behaviour of semi-closed polygonal cross-sections and gusset plate connections for the lattice section of the tower both analytically and experimentally. Finally, a lifecycle assessment was carried out and design guidelines were produced.

For additional information on the SHOWTIME Seminar to be held on 28th June and to register, please go to the SCI Events Portal.

SCI has recently completed the production of the Hi-SPAN design software which is now available from Hi-SPAN. The design software was produced in-house at SCI and includes the design of cold-formed steel purlins, rails, eaves beams and mezzanine floor joists. Automated calculation of wind and snow loads for multiple roof types are also included within the functionality of the software. All design is in accordance with latest Eurocodes, EN 1991 for loading and EN 1993 for the design of structural steel. Previously the Hi-SPAN design resistance calculations in accordance with the Eurocodes had been reviewed and granted SCI Assessed status. These design resistances are now incorporated into the new Hi-SPAN design software which is also included within the SCI Assessed scheme.

Hi-SPAN is one of the UK's leading suppliers of cold rolled products with over 55 years of experience within construction industry. Hi-SPAN offer a range of purlins, rails, channels and eaves beams designed for use in a range of situations. For information about the SCI Assessed scheme or SCI's expertise in the cold-formed steel sector, please contact Andrew Way at SCI.

Following an event to educate bridge designers and fabricators, a two hour webinar has now been released on YouTube. The webinar covers a wide range of applications and significantly focuses on primary structural sections. International speakers include Nancy Baddoo, SCI. View the webinar

SCI has recently published the third in a series of revised and updated Eurocode design guides.

Publication P364 provides a series of worked examples for beams and columns (UB and UC sections) and nominally pinned connections in buildings. Full calculations are provided, followed by a demonstration of how resistance tables may be used to speed-up the design process. This revised edition reflects the use of S355 and S460 steel for rolled sections.

In addition, the opportunity was taken to reflect the latest guidance developed since P364 was first published in 2009 - particularly relating to composite construction.

The preparation of this revised edition was jointly funded by SCI and ArcelorMittal Europe.

UK Steel Construction Day 2018: Transforming Construction: Using steel to deliver greater productivity Thursday 8th November 2018, London

The UK Government recognises that transformation in construction techniques is needed to dramatically improve efficiency in the future construction and operation of buildings and infrastructure. Steel is already ideally placed to meet these aims. This one day Event will look at recent projects taken from different sectors of the steel construction industry to showcase how steel solutions deliver cost, time and energy savings through innovations in manufacturing and digital technologies. Register for this event.

Steel Building Design: Worked Examples for Students (P387) This easy-to-read publication provides a concise overview of steel design to the Eurocodes. Although prepared with students in mind, the guide should be a very valuable reference for practicing engineers.

EOS Facades Reveal Major Investment Programme

As one of the leading steel framing systems innovators, with over 11 years expertise across all construction sectors - EOS Facades' expansion programme continues with a major extension to the company's advanced offsite manufacturing facility and the development of a new fabrication plant.

In addition to the five Howick steel framing machines currently in operation, EOS have invested in a new multiwidth (boxer) machine and installed overhead cranes for lifting and moving frames and steel coils around the extended facility. This work has been undertaken in preparation for the increased workload with the development of a complete walling solution and load-bearing panelised systems to support offsite initiatives.

Steve Thompson, Managing Director of EOS Facades said of the expansion programme: "We have invested in our own fabrication plant to be self-sufficient in manufacturing our ancillary parts such as angles, brackets, windows and cills. This will support our market leading 'lump-sum', all-inclusive pricing initiative and complement our 'total supply' offering – enabling us to support the volumetric modular building sector together with high bay and continuous walling industries.”
