Advanced Analysis Capabilities
Analysis capability is dependent upon the
product in use. For details see the Product Specification.
 Nonlinear Analysis
Nonlinear stress analysis is becoming
increasingly important with designers employing a wider variety of materials in a
multitude of different applications. Local and global nonlinear analysis with LUSAS
ensures that structures are designed economically and safely for any imposed loading.
- Geometric nonlinearity (large deformations, finite rotations
and large strains);
- Material nonlinearity (concrete, steel, rubber and
geotechnical material models);
- Contact nonlinearity (point and surface).
Automatic nonlinear solution procedures simplify the
analysis process for applications such as time-dependant dynamics, plasticity, collapse,
concrete cracking, concrete creep with recovery, contact, thermal loading, assessment of
impact, excavation and construction, staged construction, large deflection in cable
structures to name but a few.
 Dynamic Analysis
LUSAS Civil & Structural excels in solving
seismic and dynamics problems.
The natural frequency of structures, the effect of dynamic
loading, such as crowds in sports stadiums and response due to earthquake and wind loading
can all be readily calculated.
By combining the Dynamic and Nonlinear options,
nonlinear dynamic problems can be solved using implicit solution techniques.
 Thermal / Field Analysis
For large concrete structures such as cooling towers, dams
and foundation bases, steady state and transient thermal analyses can be done with or
without thermal-structural coupling.
 Staged Construction
For staged construction analysis such as in cable stayed
structures, concrete repairs, dam constuction, or excavation of material, elements can be
activated and deactivated to accurately model the construction sequence.
A CEB-FIP concrete material model to Model Code 1990 allows
creep and shrinkage to be analysed.
 Soil-structure interaction
Useful geotechnical capabilities make use of a wide range
of soil models for soil-structure interaction of piles, raft foundations, turbine bases
etc.
Residual soil stress varying with depth can be
accommodated.
Rock joints, pore water pressure dissipation, consolidation
modelling, geotechnical problems involving long term excavation, construction in clays,
and temporary works can all be solved.
