Recent developments in LUSAS have enhanced our ability to deliver a single advanced solution for any infrastructure project. LUSAS version 21.0 provides some major new facilities, extends and improves existing design and other features, and substantially advances the geotechnical capabilities. In summary it includes:
Major new facilities
Reinforced Concrete Slab / Wall Design
Reinforcement
Vehicle Load Optimisation
Rail Track-Structure Interaction enhancements
Bridge Deck (Grillage) attributes
Section property calculation
Staged construction improvements
Geotechnical
Nonlinear solution settings
General modelling, analysis and results improvements
LNG Tank System
Surfaces representing concrete and lines representing reinforcement bars
Parasitic bar elements created within host elements
Direct Method Influence Envelope dialog
VLO Optional Loading Parameters dialog.
VLO Envelope Run loadcases and associated printed results
The range of Bridge Deck (Grillage) geometric attributes that are used to define the geometric properties of specific bridge decks analysed with reference to, or derived from, grillage formulae published by Hambly and others, has been extended and enhanced. In addition to the existing Slab, Infill Slab, Girder with Top Slab and Transverse Slab with Bracing attributes, options for spaced box beams, multicellular slabs and shear key decks are now provided.
Multicellular (longitudinal beams)
Multicellular (transverse beams)
Shear key (longitudinal beams)
Shear key (transverse beams)
A tub girder section has been added to the range of plate girder section property calculators. Top flange bracing types can also be specified, allowing for easier modelling of bridge decks incorporating these girders.

LUSAS now offers more rendering options, including DirectX, to support a wider variety of modern graphics cards, providing a most robust interface, especially on machines where up-to-date graphics drivers are not always available.

These notifications and changes will allow you to continue to view results while altering a model, and also ensure that you are reminded of the need for the model to be re-solved to obtain updated results.
The LNG Tank System that allows engineers to automatically create a range of 2D and 3D finite element models of full containment circular tanks from user-defined parameters, now supports:
