This month, we share a few key statistics about Structures with you, as well as information about the initiatives the Institution and Elsevier are taking to encourage members to engage with the journal.
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
Institution Member Hugh Morrison presents a follow-up to May’s question on forces in a canopy.
The Helix is a 280m pedestrian bridge in Singapore connecting the promenade at Bayfront and the Marina promenade. It forms part of a 3.5km waterfront promenade that loops around Marina Bay. Built using duplex stainless steel, the bridge has a unique curved helical geometry which consists of two intertwining helices that spiral in opposite directions. It was designed by a team comprising global consulting engineers Arup, and architects from the Australian Cox Group and Singapore-based Architects 61.
Due to its location in the centre of Marina Bay, Singapore’s new downtown area, there are many possible usage scenarios for the Helix in addition to its primary function of providing pedestrian access. These include:
a crowd gathering on one side of the bridge to view a firework display; and the bridge acting as a sports or events venue, e.g. for marathons or performances. The complexity of possible loading scenarios also extends to the accidental impact force from vessels in the bay. The Helix’s structurally efficient long-span form, coupled with its long cantilever viewing pods and the possible functioning scenarios, meant that the structure’s dynamics and vibration performance were a major design consideration to ensure user comfort.
