(Corrigendum: On p. 40 the return periods for basic design wind speeds in Singapore should have been given as 50-year and 100-year, not 50-year and 1000-year. The article was updated on 3 March 2017.)

Are codified serviceability and stiffness criteria appropriate in a world increasingly focused on reducing material use and embodied carbon? Could new approaches to loading and movement offer ways to meet these goals? Does modern technology create the potential for adaptive designs which actively control deflections? This paper explores ways in which the structural engineering profession could move towards a truly performance-based design approach, drawing on examples from the work of Expedition Engineering and other engineers.

A review of CROSS (Confidential Reporting on Structural Safety) and press reports suggests that lack of stability during construction is a prime cause of accidents. In May 2016, the centre section of a new elevating bridge at Barton on the Manchester inner ring road in northwest England collapsed while being tested. The failure can be viewed online. While the cause has not yet been published, it is clear that the lifting process was uncontrolled. Other reports in CROSS discuss concerns about the stability of steel frames during concreting.

This article proposes element design equations for typical loading conditions on a bamboo culm: flexure, shear, axial tension, axial compression and local bearing. The work draws on existing published bamboo and timber design codes, and sound engineering judgement.

Structural engineers are well versed in applying codes and standards to ensure that structures meet rigorous safety and durability requirements. However, the design, construction and operation of moving structures can be a very different discipline, often closer to the mechanical engineering design of a bespoke machine than to traditional structural engineering. This article outlines key considerations for any structural engineer involved in the conception, design and delivery of moving structures, and provides advice on seeking specialist support.

This article looks at the calculation of across-wind response of structures. The focus is on the calculation of cross-wind response of rectangular buildings, which is not covered by Eurocode 1, Part 1-4 (BS EN 1991-1-4) (ref 1) or BS 6399-2 (ref2). With the advancement of building technology and an increasing number of architecturally driven designs involving more free-form geometry leading to tall, slender, lightweight, low-damping and aerodynamically sensitive building structures, this article presents a timely discussion on an important topic that could impact on structural design.

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 benefit 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

Readers are reminded that the latest issue of Structures is a special issue presenting selected papers from the 11th International Conference on Advances in Steel-Concrete Composite Structures (ASCCS 2015), held in Beijing, China, on 3–5 December 2015.
