Available for purchase
to increase the analysis and design capabilities of LUSAS Civil
& Structural plus:
Steel
Frame
Design
- Design code-based results
visualised as Utilisation ratios on members
- Design summary results
produced for selected members and loadcases
- Generate formatted design
reports, showing calculations made and referencing clauses
and equations from chosen code
RC
Frame Design
- Design checking of regular and arbitrary shaped reinforced
concrete members subject to bending and
axial force
- Design code-based results
visualised as Utilisation ratios on members
- Produce a tabular summary of results for selected members and loadcases,
view detailed results and generate interaction diagrams
RC
Slab / Wall design
- Comprehensive
design checks to a large range of international Codes of
Practice
- Strength/ULS and SLS checks
based on flexural, twisting and in-plane effects, shear,
stress limits, minimum and maximum areas of reinforcement and
crack widths or spacing considerations as appropriate for all
supported codes
- Allows for defining load
combinations for each design check separately and produces
contoured results, detailed table results and rendered
calculations for adding to reports

Heat
of Hydration Analysis
- Models the heat of hydration
of concrete for a variety of cement types.
- Includes effects due to the
addition of fly ash and ground granulated blast furnace slag
- Permits hygro-thermal analysis
to determine time- and age-dependent deformations, stresses,
crack-widths and more.
Composite FRP
- For structural and bridge applications, modelling of Fibre Reinforced Polymer (FRP),
laminated glass, reinforced concrete using
the smeared reinforcement technique, and gradual
through-thickness masonry arch cracking assessments can be carried out using
advanced layered shell elements.
