Advanced elements, materials and
solvers
Unrivalled
state-of-the-art linear and quadratic element libraries; advanced
material models; linear, nonlinear and seismic isolator joint models;
direct and eigen solvers, and a fast solver option collectively allow
all types of bridge engineering problem to be modelled and solved as
efficiently as possible.
Advanced element
libraries
- Plate and shell
elements for slab decks
- Beams and shells for
prestressed concrete, steel and composite construction
- Solid elements for
detailed modelling and studying local effects
- Elements for cable
stayed and suspension structures
- Joint elements for
linear and nonlinear joint models
Additional element information is given on
the product specification page.

Advanced general
material models
- Isotropic including
plastic, creep, damage, shrinkage, viscous, two-phase
- Orthotropic
including plastic, creep, damage, shrinkage, viscous, two-phase
- Anisotropic and
rigidity models
- Temperature
dependent models
- Concrete models with
opening and closing of cracks, concrete crushing, and strain
softening based on fracture energy in 2D/3D
- Concrete creep
including AASHTO LRD 7th Edition, CEB-FIP Model Code 1990,
EN1992-1-1:2004 Eurocode 2, IRC:112-2011 and creep only for Chinese creep model
code.
- Geotechnical models
include Tresca,
Von Mises, Drucker Prager, Duncan-Chang,
Modified Cam-clay, Mohr Coulomb criteria with non-associative flow for
soils and rocks, Volumetric
deformation soil model (includes consolidation)
- User-defined models
and others
Joint material models
Joint material models
are used in conjunction with joint elements to fully define the
properties for linear, nonlinear and seismic isolator joints.
- Linear joint models
include those for spring stiffness only and for general joint
properties having spring stiffness, mass, coefficient of linear
expansion and damping factor. User-defined force/displacement and
axial force dependent curves are supported.
- Nonlinear joint
models include elasto-plastic uniform tension and compression with
isotropic hardening, elasto-plastic general with isotropic
hardening, smooth contact, frictional contact, nonlinear
user-defined, matrix properties, and others.
- Seismic isolator
joint models include viscous dampers (Kelvin and Four Parameter
Solid), lead rubber bearings with plastic yield and biaxial
hysteretic behaviour, friction pendulum system with pressure and
velocity dependent friction coefficient and biaxial hysteretic
behaviour, and others.
Solvers
A Fast Solvers option
(supplied with all new sales) provides a range of state-of-the-art
solvers for use with all LUSAS Bridge software products.
