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.

EQpic1

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).

Oasys Xdisp for building and utility damage assessment arising from ground movements

Xdisp Image

Oasys Xdisp has transformed the ease and speed of calculations of ground movements arising from tunnelling and embedded wall excavations, and of subsequent building and utility damage assessments.

The latest release of Oasys Xdisp (Version 19.4) provides improved utility damage assessment calculations.  Pullout and rotation are assessed for jointed utilities. Strains are assessed for both jointed and unjointed.  Separate factors may be applied to rotation, pullout and strain results.

The program has been upgraded from 32 to 64 bit, so with greater speed very large data sets can be analysed and their results interrogated.

Xdisp now reads Pdisp data files, enabling building and utility damage assessment calculations in Xdisp using ground movement results from Pdisp (i.e. from imposed loads), or using the combined ground movement results from both Xdisp and Pdisp analyses.

Xdisp allows both specific and generic damage results to be calculated.  Generic results give an initial view of the likely areas of concern, without the need for precise building or utility damage locations.

Visit oasys-software.com/xdisp for more information and to download a free 30-day trial.

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 .

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.

Lanhua_Building_Beijing_Camera_Vision_Studio

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.

MassMotion evacuation modelling validation for the elderly

In collaboration with research partners, Carleton University undertook a study to developCarleton University a baseline for the behaviour and actions of the elderly during pre-evacuation and movement stages of emergency egress situations. The resulting research paper critically examines a fire drill performed in 2016 at a retirement home in Canada and provides insights and guidance into the modelling of elderly populations.

A comparison was then made between the data collected during the fire drill and with associated evacuation modelling results using Oasys MassMotion, resulting of three different types of evacuation trails using the software.

The research has been presented at the Interflam 2016 conference and will also be presented at the 8th International Conference on Pedestrian and Evacuation Dynamics (PED2016) in October 2016.

How the University of Sheffield encourage Structural Engineering in Higher Education

As part of the Annual Academic’s conference held at the Institution of Structural Engineering in September 2016, the University of Sheffield were invited to present.

They gave a fascinating presentation on “The Extra Curricular Activities at Sheffield” which outlined how they use extra-curricular activities in Structural Engineering in Higher Education.

The University of Sheffield offer these activities to develop creativity and to help their students CV’s outshine competitors. In this they demonstrated how Oasys GSA software is used outside their core syllabus by students on design projects.

The slide below was presented at the conference to show how GSA was used as part of the detailed design stage of a ‘Bridge Club’ project.
