Dynamic crowd modelling for better stadium design


The design of sports stadia has been front of mind with the general public again with projects like Tottenham Hotspurs’ new Stadium due to open for the 2018-19 season and, on a more sombre note, the UK’s Hillsborough inquiry having reminded us what can go wrong.

40 tonne sculpture wins recognition for engineering excellence

The Hive GSA

The winner of the award for small practices in the Institution of Structural Engineer’s 2016 Structural Awards was Tristan Simmonds of Simmonds Studio for The Hive open air sculpture. Engineered using Oasys GSA the sculpture was originally designed for the British Pavilion at the Milan World’s Fair Expo in 2015 where it attracted over 3 million visitors and subsequently won the prestigious Gold medal for architecture and landscape. It is now open to the public at the Royal Botanic Gardens in Kew.

Manchester City’s expanded stand wins engineering award

MC Stadium_Buro

GSA-user Buro Happold Engineering’s work to expand the South Stand at Manchester City Football Etihad stadium South Stand was recognized as the best sport/leisure project in the 2016 Institution of Structural Engineer’s 2016 Structural Awards.

The new 6000+ seat third tier opened in August 2015, in time for the start of the 2015–16 football season. Work on a third tier for the North Stand is expected to begin by 2017, increasing total capacity to around 61,000.

Peter Debney joins Hugh Morrison as speaker at IABSE ‘Future of Design’ Conference 2017

The full-day conference takes place on the 21st April 2017 at the University of Sheffield and hopes to inspire future generations as well as promote the fundamentals of design. It is the first time IABSE, the International Association for Bridge and Structural Engineering, are hosting an event in Sheffield.FoD

Hugh Morrison of Hugh Morrison Associates and author of the acclaimed ‘Structural Engineering: Art and Approximation’ book, invited Oasys Application Specialist, Professor Peter Debney, to join him present a section of the interactive workshop. The aim of the workshop is to demonstrate how approximation of the structural behaviour of a long-span structure using hand calculations can provide an understanding of its dynamic response. The example structure used is the Merchant’s Bridge in Castlefield, Manchester with Oasys GSA being the software of choice to validate the delegate’s results.

Join them both by registering for the conference.

You can download the workshop proposal here.

“Inspiring, eye-opening, challenging and hugely rewarding. Engineering and architecture superstar speakers talking about mind blowing projects… a must attend for all young engineers”.
Antony Oliver, Infrastructure Intelligence – describing a previous Future of Design conference.

Perth pedestrian bridge wins more accolades

As sponsors of the Pedestrian Bridges category in this year’s Institution of Structural Engineer’s 2016 Structural Awards we were particularly pleased that the judges chose a project designed using Oasys GSA software.

The Elizabeth Quay Bridge in Perth, Australia is part of a bold plan to revitalise the city centre, returning its focus to the Swan River and providing a world-class waterfront destination. GSA was used for form finding, to predict footfall-induced vibration and to work powerfully and flexibly alongside parametric modelling software that maintained consistent relationships between elements as a complex and innovative model was manipulated.


The striking 22m high, 110m cable-stayed bridge is the project’s centrepiece feature. Two 45m spans connect in the middle, with the bridge’s arches sweeping down towards the water to rest on concrete piers supported on piles socketed into the rock bed. The curved form for the bridge deck allowed for extended, gently-sloping pedestrian ramps to clear the navigation channel which required a mean clearance of 5.2m.

The design excellence has resulted in a 110m bridge that responses exceptionally to the Metropolitan Redevelopment Authority’s ore brief of an iconic structure that is timeless and refined in its simplicity. The Elizabeth Quay Bridge was awarded an Engineers Australia Award for Excellence 2016 (Buildings and Structures) and an Australian Steel Institute, Steel Excellence Award 2016 (Engineering Projects).

Determining the number of repeat simulations during evacuation/pedestrian modelling

At the MassMotion User Group Day held at the Institution of Structural Engineers (London, UK) in September 2016, Dr. Michael Kinsey from the Arup Fire Shanghai office presented a talk entitled ‘Evacuation/Pedestrian Modelling: Methods for Determining the Number of Repeat Simulations’. Michael’s presentation was recorded and is available for you to watch below.

The talk initially provides an overview of what are random numbers and broadly how they are generated. The motivations for utilising random numbers are then discussed along with common aspects of evacuation/pedestrian modelling which use such values along with the justification for needing to run repeat simulations in the modelling process. A broad overview of methods for determining the number of repeat simulations is then presented along with some techniques which can be employed to potentially reduce the number of repeat simulation runs.

For any questions please contact Dr Michael Kinsey: Michael.Kinsey@arup.com .

MassMotion gets attendees talking and blogging at CanBIM – Live presentation recording


MassMotion Product Director Erin Morrow spoke at the CanBIM Regional Session & Technology Exhibition about the continued development of the two Oasys pedestrian simulation programs, MassMotion and Flow. The talk was titled ‘Putting (Virtual) People First in Design’.

Erin’s presentation got audience members talking and with one member in particular. Geoff Zeiss, Principal at Between the Poles, a thought leadership consulting firm, was so impressed he’s blogged about Erin’s presentation and the software he was presenting. We like your work, Geoff!

Oasys Adsec load analysis now compatible with Indian and Canadian design codes

The 8.4 version release also includes an improved interface and now enables engineers to edit and query models from within graphics. A new release of Oasys AdSec, the leading analysis program for sections under load, is compatible with a wider range of international design codes. The list now include Indian IRC and Canadian CSA standards alongside the Eurocodes.


Additional material models are built in to the new release and standard curves are provided as templates. This makes it easier for users to edit, adjust and test the use of different materials and combinations.

Oasys AdSec can handle sections made from concrete, steel or fibre-reinforced polymer (FRP), or any combinations of these materials. It is ideal for both new build projects, for instance designing a composite mega column or checking a pre-stressed floor, and refurbishments where it can reveal the potential for improving existing beams and columns. Oasys AdSec users can combine long-term dead loads with short-term imposed loads

Oasys AdSec is frequently used in conjunction with other Oasys programmes including Pile for analysing vertical load capacity, ALP for lateral pile loading and Frew for retaining wall analysis.
