The winners of The Structural Awards 2016 were announced on 11 November during a ceremony held at The Brewery in London. Over 380 people attended the event, which was hosted by BBC presenter Clive Myrie.
In a paper based on his 2016 IABSE Milne Medal Lecture, James O'Callaghan reflects on his career as an engineer and, in particular, his interest in the art of structural glass design – a field in which he is widely acknowledged as an authority.
James illustrates the evolution of glass as a structural material over the last 20 years and considers its future in an industry increasingly focused on energy efficiency.
The Milne Medal is awarded annually to an individual engineer for excellence in structural design, both in the overall concept and in the attention to detail in their work, and is named in recognition of the late Bob Milne, who served for many years as the Honorary Secretary of the IABSE British Group.
The Etihad Stadium was initially constructed for the Manchester Commonwealth Games of 2002, with the original stadium comprising reinforced-concrete terrace structures that supported a lightweight cable-stayed roof. The stadium underwent a planned conversion following the games to become the 48 000-seat home of Manchester City Football Club. It opened in August 2003 in time for the first home game of the season, before officially becoming the Etihad Stadium in 2008.
In 2012, following unprecedented growth and development, the club took the decision to expand the stadium to a capacity of 55 000. In contrast to the previous conversion, the design and construction teams had to extend one end of the stadium without compromising the structural integrity of the roof to the
remaining three stands.
Part 1 of this paper described the engineering design led by BuroHappold Engineering. Part 2 covers the challenges faced by the fabrication and construction teams (Laing O’Rourke and Severfield). These relate to the programme sequence and construction methodology, and resulted from the key objectives of:
• completion of the works for the start of the 2015/16 season
• maintaining a roof over spectators
• no seat loss on match days during the football season
• minimal disruption to the stadium operations
The paper will describe the inventive techniques developed to resolve these challenges, including the temporary works for erection of the roof.
We conclude the series on professional indemnity claims from Griffiths & Armour with a look at what engineers can gain from a post-loss review.
This article covers the hazards associated with ground movement, and how this can be mitigated through detailed risk assessments.
This article summarises CROSS newsletter No. 44 from Structural-Safety.
This article explains the theory and background to backpropping and gives advice on the methods recommended to be adopted for backpropping calculations.
This third article offers an up-to-date guide for determining design values for bamboo elements.
Irish engineer Victoria Janssens has recently applied her talents in Hong Kong on the Zaha Hadid-designed hotel tower at the City of Dreams, Macau, and on the Mercedes-Benz Stadium in Atlanta – all thanks to a decision to risk working overseas. She talks to Jackie Whitelaw.
In a rallying cry to the profession, Balazs Trojak explores the changing role of structural technicians and looks forward to a bright future that is theirs to shape.
This new handbook offers a good grounding in the practicalities of BIM, says Laura Norris, thanks to its structured approach, with good, solid advice gleaned from industry experts working in the field on a daily basis.
Bob Lang finds this to be an intriguing and informative text on the design of tall buildings and is particularly drawn to the structural details from real-life projects which demonstrate the consequences of engineers’ decisions.
The fate of the Eurocodes in the light of Brexit, and professionalism among engineers, are just two of the topics that have sparked readers into putting pen to paper this month.
Upcoming events at HQ and around the regional groups.
In this section we shine a spotlight on papers recently published in Structures – the Research Journal of The Institution of Structural Engineers.
Structures is a collaboration between the Institution and Elsevier, publishing internationally-leading research across the full breadth of structural engineering which will benefi t from wide readership by academics and practitioners.
Access to Structures is free to Institution members (excluding Student members) as one of their membership benefits, with access provided via the “My account” section of the Institution website. The journal is available online at: www.structuresjournal.org
This month we bring you a question from the Institution’s Structural Behaviour Course on deflected shapes. The answer will be published in the January issue.
