"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."

"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."

West Gate Bridge Upgrade
Strengthening of a major steel box
girder bridge for additional traffic loading, by cantilever
propping, internal stiffening, and post-tensioning; and
management of construction loads.
|
|
"Having
a single global shell model meant that there was no need to worry
about specifying boundary conditions or applying suitable loading
as would be required for looking at regions of the structure using
separate localised models, and this was a big plus."

Project Engineer, Flint & Neill

"Modelling
each stage of construction in LUSAS facilitated accurate geometry
control and allowed us to confidently monitor the pylon bending
demands."

Mersey
Gateway Bridge
- Analysis of an illustrative design
of a 3-tower cable stayed bridge using line beam modelling to
investigate global effects and a staged construction analysis to
prove the design.
|
|
Ramboll was appointed Lead
Consultant and Project Manager by Halton Borough Council to carry
out a route identification study and illustrative design for a new
crossing of the River Mersey in the UK. To assist with its
development of the proposed new bridge Gifford used LUSAS bridge
analysis software to carry out analytical studies to prove its
draft design.

“LUSAS proved to be
a valuable tool for the project. We especially enjoyed
the ability to model the various stages of construction and in-service
loading."

Making the most of Eurocodes for critical buckling analysis
|
|
"Not only did the nonlinear
LUSAS model give results almost identical to the actual physical
test specimen but it also showed that the EN 1993-1-5 rules for
stiffeners were very conservative for this particular beam, and
the BS 5400 Part 3 predictions even more so."

Semi-automated design
of composite bridge decks
|
|
"Many
composite bridges have been analysed by Alhambra using LUSAS
Bridge, and in doing so the number and quality of the wizards
created and used for this purpose has increased so that they have
now become a very productive modelling tool."

Cable
stayed bridge over the River Labe at Nymburk
|
|
"By using
LUSAS on this project we obtained an accurate assessment of the
deck displacements caused by the static and dead loads. The
easy-to-use modelling capabilities and the re-use of previously
defined load patterns helped enormously with this."

Deck segment analysis for the Yi
Sun Sin Bridge
|
|
Using LUSAS, all webs, flanges, ribs
and other small members in the 6 metre long deck segment were
modelled. From the detailed
LUSAS analysis it was seen that the main structural behaviour was in
the transverse direction, and, as result, it was seen that the initial
diaphragm design needed to be strengthened.

Redesign of Estero Parkway Flyover
- Steel box girder redesign
of a two-span bridge resulting in large construction
cost savings for the client.
|
|
"The use of LUSAS helped us
meet our design deadline and to prove an alternative bridge design
that will ultimately save the client a great deal of money in
construction costs."

Advancing Segmental Bridge Technology
- Analysis and optimization
of post-tensioned precast concrete bridge segments
|

"LUSAS Bridge has been a
great tool for us on this project. It allowed us to produce a
design that has major benefits for the client and contractor. We
would recommend its use to others wanting to enhance their
in-house design and analysis capabilities".

Wichita's Riverfront

- Staged erection analysis
of two complex post-tensioned bridge structures
involving 3D linear and nonlinear analysis and cable
tensioning optimisation.
|

"We used LUSAS Bridge
exclusively for the erection engineering of the Wichita
Bridges and obtained excellent correlation between the
on-site cable stayed measurements and the values that LUSAS
predicted for lift-off"
