LimitState MD presents at the Surveyor Bridges conference

In his presentation entitled ‘Masonry arch bridges - Where are we?’ at the 2009 Surveyor Bridges conference, Dr. Matthew Gilbert, MD of LimitState and also Senior Lecturer in the Department of Civil and Structural Engineering at the University of Sheffield outlined the strengths and weaknesses of current analysis and assessment methods for masonry arch bridges and also presented recent research findings, including those from work undertaken at the Universities of Sheffield and Salford funded by the UK County Surveyor's Society.

Update - Masonry Arch Analysis Seminars

Many thanks to all those who attended our recent seminars on Masonry Arch Analysis - it was good to meet so many people. For those of you who were unable to make it to make it to Birmingham, Sheffield or Bristol we hope to run further seminars ln the future, so please keep a lookout for announcements on these pages.

ring2.0 featured in 'The Structural Engineer' magazine

ring2.0 was recently the subject of a 3 page article in 'The Structural Engineer' - the magazine of the Institution of Structural Engineers. The piece highlighted how ring2.0 can help the engineer understand how a masonry arch carries load, how it might fail if overloaded and also rapidly answer the kind of ‘what if’ questions engineers often face

FREE Seminars on Bridge Analysis & Design

Following on from a highly successful event in Manchester last year, LimitState and Bestech Systems Ltd are teaming up once again to hold a series of free morning and afternoon seminars on bridge analysis and design in the following venues:

21 May
London
Institution of Structural Engineers
4 June
Glasgow
Marriott Hotel
25 June
Dublin
Marriott Ashbourne (Airport)

The afternoon sessions will be devoted to 'Analysis of masonry arch bridges', whilst the morning sessions will be on 'SAM-LEAP5 the integrated bridge design software'. Both seminars are entirely free and people are most welcome to come along to one, or both.

Afternoon Session: 'Analysis of masonry arch bridges'

Who Should Attend?

The seminar is designed to benefit practising senior bridge engineers, bridge engineers, civil engineers and consultants. Topics will be relevant to both potential and current users of masonry arch analysis software.

What Will be Covered?

Masonry arch bridges are ubiquitous yet many engineers freely admit to not adequately understanding how they behave. In these seminars we will demonstrate that ring2.0, a state-of-the-art analysis software program, permits both rapid assessment of masonry arch bridges and also allows the user to gain a much better understanding of how these bridges work.

Last year we ran similar seminars in Manchester, and they proved to be very successful. At the time many people requested that we also arrange seminars in other locations, and we are now pleased to be able to offer the above dates / locations.

After outlining the theory and experimental validation work which underpins ring2.0, we will use case studies to demonstrate how the software can be applied to bridges in the field. The seminars will include live demonstrations of the software so that you can see just how easy it is to use. As one engineer told us recently, "ring2.0 is faster and easier to use than MEXE!"

ring2.0 features to be explored will include:
  • Multi-span bridge analysis
  • Railway underbridge analysis
  • Identification of mechanisms involving sliding failures
  • Localized loss of mortar
  • Settlement analysis

These features in ring2.0 enable you to model masonry arches more accurately than has been the case before, in many cases revealing that a bridge has higher capacity than originally thought.

The originator of the software, Dr Matthew Gilbert of the University of Sheffield and LimitState Ltd, will be on hand to answer questions.

To Register

For more information or to register for the afternoon session, please email ring2-seminars@bestech.co.uk

Morning Session: 'SAM-LEAP5 the integrated bridge design software'

SAM-LEAP5 is a suite of integrated software modules that allow you to design road and rail bridges. In recent times it has changed dramatically, for example:
  • A new interface for the analysis module has made it more powerful than ever.
  • The software now incorporates Eurocodes, as well as designing to BS 5400 and the DMRB.
  • A new post-tensioned beams module has been added.

This short seminar will allow you to catch a glimpse of the full power of this bridge design software, and hear about our Eurocodes implementation. We will cover what the program does, how it links together, and will show a short demonstration to show some of the more useful benefits, especially that of using software to help you with Eurocode training.

To register, or for more information, please email sam-leap5-seminars@bestech.co.uk

Manchester ring2.0 seminar - Wednesday 21st November

On 21st November, LimitState and Bestech Systems presented a series of seminars on the analysis of masonry arch bridges. Held in the welcoming environment of the Etrop Grange Hotel, the event was well received, attracting over 50 delegates, each discovering how they can use ring2.0 to rapidly and reliably analyse masonry bridges. The creator of ring, Dr Matthew Gilbert, was in attendence to present and also field questions from the audience. A PowerPoint copy of his presentation is available for logged-in users to download [20.2Mb].

ring used in prize winning paper

ring was successfully used to predict the detrimental effect of flooding on masonry arch bridge strength in an award winning ICE paper:

"Load-carrying capacity of flooded masonry arched bridges."

Predictions from the software were in close agreement with those from laboratory tests for dry and flooded model arch bridges.

Whilst the potential for fast flowing water to undermine bridge foundations is well known, this study involved replicating the situation of a submerged bridge lying in a flood plain. Given the increasing prevalence of flooding worldwide, and the very large numbers of masonry arch bridges still in service, this was a timely study.

Co-authored by Penn-State University researcher Kent Hulet (pictured), LimitState co-founder Colin Smith and ring originator Matthew Gilbert, the paper was awarded the Baker Medal, one of the Institution of Civil Engineers most prestigious awards, named after the notable Forth Railway Bridge engineer, Sir Benjamin Baker.

ring2.0 has been launched!

ring2.0 was given its official launch at a seminar on masonry arch bridges held at UIC (International Union of Railways) headquarters in Paris on 9th May 2007. The venue was fitting given that ring2.0 was developed from the outset in co-operation with UIC. In attendence at the meeting were representatives from railway companies and other organizations from across the world.
