Case Studies - Soil-Structure Interaction Modelling
LUSAS
is used by engineers worldwide for all types of soil-structural
interaction modelling.
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.

Integral bridge
analysis and design to EC4
|
|
"The use of
LUSAS with nonlinear joints modeling the active and passive
pressure allowed us to have an integrated model of the deck and
the abutments that will be used also for seismic analysis. The use
of the steel and composite deck designer was mandatory to enable
us to optimize the design in a reasonable amount of time in
accordance with relevant Eurocodes."

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."

Regional Head of Bridge Engineering, Atkins

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."

Integral
abutment bridge design
- Global analysis and soil
structure interaction of an integral abutment bridge
structure
|
|
"Abutments
are of reinforced concrete with steel piles and deck girders
embedded in the bank seats transmitting end fixing moments
from the deck into the piles. Thermal deck movements are
accommodated by soil structure interaction between the piles
and the surrounding strata, resulting in flexure of the
piles about their weak axis of bending."

Vasco da Gama bridge and
approach viaducts
- Pile/soil interaction and
seismic analysis of a cable stayed road bridge and
associated approach viaduct structures
|
|
"In the substructure
analysis, soil degradation was a key consideration and this
required an iterative analysis procedure. 2D plane strain
finite elements were used to model the soil, together with
constraint equations to ensure that only shear deformation
was considered."

Söderström Tunnel Connector
- Detailed solid modelling and
nonlinear contact analysis of a cable anchored concrete tunnel
connector and the surrounding rock to prove the stability of the
connector for all considered loading conditions
|
|
Load
transfer mechanisms between the concrete tunnel and the rock were
investigated to ascertain the magnitude of stresses and forces at the
connection, in the anchorage cables, and in the rock itself due to
permanent, variable and accidental loading to the immersed
concrete tunnel.

Nonlinear contact joint
elements were used to model the lift-off and frictional
sliding at the foundation, stop-block and shear-key
interfaces. Additional joint elements were used to provide
hydrodynamic mass and damping actions on the walls and
base-interface.
