Rail Projects
LUSAS Bridge
is used by engineers worldwide for all types of rail bridge analysis, design
and assessment / load rating.
These case studies
show illustrative uses of the software, with the most recently
added article at the top. Country flags relate to the project's
location.

"Generating
a full 3D finite element model using LUSAS allowed us to
complete the design rapidly and efficiently, and
optimize the section sizes with high precision."

"LUSAS
is my first-choice tool for any of the structural
analysis we do. For the non-standard work we undertake
we need a general-purpose finite element analysis
package that is not narrowly tailored to a particular
market segment. LUSAS fulfils that role, letting us
analyse and design with materials or for applications
not yet well defined in civil engineering codes."

Director, Tony Gee and Partners

"An
independent verification of the thermal interaction results
obtained using LUSAS for the Rowlett Creek bridge was carried out
by engineers in another Gannett Fleming office using different
software. The results were strikingly similar, verified the LUSAS
modelling method, and illustrated just how efficient LUSAS is at
modelling track-structure interaction effects for these types of
bridges."

BEBO Arch System
Modelling

"BEBO engineers have a lot
of experience in the use of finite element analysis software, not
only for the design of projects involving soil-structure
interaction, but also for a variety of materially nonlinear
analysis, particularly of reinforced concrete structures. To
assist us with the design of our range of BEBO Arch Bridge
Solutions, and for our general structural analysis requirements,
LUSAS meets our needs perfectly."

Director, BEBO Arch International AG

Seismic
analysis of viaduct substructures on the Dubai Metro
|
|
"The use of precast
concrete elements for the deck and for key substructure
components, and the use of LUSAS software to assist with our
design process, all helped to ensure that the viaduct construction
progressed as planned."
David A Smith,
Regional Head of Bridge Engineering, Atkins

Analysis
and design of footbridges for the Dubai Metro
|
|
"The use of a modular
design approach in conjunction with detailed LUSAS analyses of the
main footbridge types enabled us to design the large number of
footbridges required for the project in a very timely and
efficient manner."
David A Smith,
Regional Head of Bridge Engineering, Atkins

Rail
track / structure interaction analysis for the Dubai Metro
|
|
"By using LUSAS to
investigate these span arrangements we got a more accurate
assessment of the rail track interaction effects and obtained
values that did not exceed design criteria"
Rachel Jones, Atkins

Rail track
interation analysis for the Honan high speed railway
|
|
"Correct modelling of the
nonlinear behaviour of ballast, and of the interaction between the
ballast and the rail track is not easy to do manually, so the
LUSAS Rail Track analysis option, which handles this
automatically, was very useful to us in this respect".

Engineering Manager, Saman Engineering

Automated track-structure interaction
analysis
- Fast assessment of
track/bridge interaction forces in rails from thermal
and in-service train loading
|
|
A LUSAS product option,
permits track-structure interaction analysis to the
International Union of Railways Code UIC 774-3. It allows
models to be automatically built from data defined in MS
Excel spreadsheets, an analysis to be run, and results
rapidly obtained in spreadsheet or LUSAS results file
formats.

Taiwan High Speed Railway
- Pile-soil interaction
modelling and automated model building for multi-modal
spectral response analysis of viaduct structures
|
|
"The
versatility of LUSAS Bridge coupled with the technical
expertise within our Group helped produce an economical
design for the extreme seismic performance criteria of the
Taiwan project with its demanding programme and construction
constraints."

Neasden Lane overbridge
- Successful linear analysis
re-assessment of bridge deck previously failed for 40
tonne vehicle loading
|
|
"We found it
quick and simple to upgrade an existing model in order to include
new features or de-activate existing ones within a 3D model. In
addition the results processing facilities were particularly
useful in identifying the critical areas of the deck." Sameer Khan,
Senior Engineer, Tony
Gee & Partners

Forsmo Bridge
- Assessment of a steel
truss arch railway bridge using iterative model
development from strain gauge results to assess
Ultimate, Serviceability and Fatigue Limit States.
|
|
"Ramboll successfully
used strain gauge measurements on the Forsmo Bridge in
Sweden to fine-tune a LUSAS Bridge model prior to
carrying-out an in-depth assessment of the structure for a
proposed increase in freight train axle loading."

Newark
High Speed Rail Bridge
- Detailed dynamics analysis
using Interactive Modal Dynamics techniques
|
|
"The Interactive Modal Dynamics (IMD) techniques used greatly
reduced the time required to assess the dynamic response of
the structure for numerous combinations of different moving
train loads and speeds."
