Recipient of IABSE's 2012 Milne Medal, Simon Bourne, draws on 30 years of bridge design experience, to encourage engineers to consider simplicity over complexity when designing post-tensioned bridges. This paper is based on Simon's Milne Medal Lecture.
This paper describes the design process adopted by Arup and Foster + Partners, who were commissioned to design a new winery in Spain. Each step of the design process, from establishing the organisational diagram for the wine making and visitor experience, through to design of the structural systems required to achieve the architectural vision is explained. The project was shortlisted for one of the Institution's 2011 Structural Awards.
A number of Health and Safety Regulations are frequently encountered by structural engineers in Great Britain. Many of these address specific safety and/or health risks and can be used as a source of information for engineers during the design process.
Following a period of consultation with industry, two key UK Government documents were published in 2012. Kevin Eaton describes how both will impact the way contaminated land is asessed and managed.
Aimed at junior engineers, Andrew Briggs encourages a structured approach when trying to assimilate design instuctions.
This guidance note describes the different types of pile presently in use, the design concepts that are employed when determining their size and depth, how they are constructed and the various tests that can be carried out to assess a pile's integrity.
The subject of this guide is the design of columns in simple construction to BS EN 1993-1-1 – Eurocode 3: Design of Steel Structures – Part 1-1: General Rules for Buildings. It covers rolled steel ‘I’ and ‘H’ sections that are acting as columns within a braced steel frame structure.
The design and usage of pedestrian structures has changed substantially in recent years, leading to an increase in problematic post-construction vibrations due to in-service loading. One alternative technology that could be used to help mitigate this problem, particularly in floor structures, is active vibration control (AVC). While relatively mature for the full-structure control of seismic- and wind-induced vibrations, its application to floor structures is in still its infancy. This paper uses field trials and a small number of implementations to illustrate the significant potential for the technology in this area.
Several reports of offshore wind turbine topside structures settling on their monopile foundation structure have come to light. In response, a joint industry project was initiated by Det Norske Veritas (DNV). It found that the axial capacity of the grouted connections is more sensitive to the diameter (capacity reducing more than predicted at larger diameters) and surface tolerances than had been accounted for in the existing design standards. This paper reviews the past and present industry practice relating to the design of grouted connections in monopile structures. The physical behaviour of the connections is explained and some of the most critical issues relating to the design of large diameter grouted connections are assessed.
Nearly three years after they were introduced, to what extent are Eurocodes really being implemented in the UK? CSC's Chief Engineer, Alan Rathbone, discusses the progress the industry has made to date and encourages UK engineers to be at the forefront of these changes.
Bristol University's Adam Crewe hold a new book, from leading seismologist Roger Musson (British Geological Survey) in high regard.
