Fast Frame Geometry Input
Productivity is enhanced by an extensive selection of 2D and 3D frame generator macros. Users follow a simple procedure, entering the frame or truss dimensions and properties with the program producing the complete frame geometry in a few seconds. Additional sub-frames and individual members can be added, as required.
Information at Your Fingertips
To maximise productivity, A3D MAX allows users to access all data, including geometry, section properties, loads etc., at the touch of a button. When used in conjunction with the extensive on-screen help, the software is very easy to learn, and suitable for occasional users. Wading through reams of results can be a big headache, so the Deflection Limits facility is provided to filter out trivial results and report only the ‘critical’ or ‘failed’ deflections as defined by the user.
Excellent Printing Facilities
Every experienced user of engineering software will know that getting appropriate printed output from their application can be less than easy. This should not be a problem for CADS users because only the input data and calculations results required by the user are printed. Before output is committed to the printer it can be can checked by using the ‘print preview’ facility.
Links to Design and AutoCAD
A3D MAX can also be integrated with other engineering software from CADS or other suppliers. Regarded as an integral part of a larger software solution, A3D MAX is frequently chosen from a selection of other analysis programs because of its suitability for a particular job.
The CADS Reinforced Concrete Solution offers links to CADS RC Design modules for RC beams, columns, bases and pilecaps, through to CADS RC detailing and automatic bar scheduling with AutoCAD. The CADS Steel Design Solution offers links to BS 5950 steel member and connection design, through to CADS Steelwork detailing and scheduling, popular with consulting engineers and steel fabricators.
The CADS Design Wizard allows members and supports to be grouped for common design and batch processing of steel members and concrete bases.
The software provides designers with an option to ignore the torsional stiffness of the frame members where torsion is not a primary load path. The removal of torsional moments from the frame is balanced by an increase in some of the bending moments. This simplified analysis is permitted by BS 8110 Part 2 Clause 2.4.1 and is mainly useful in reinforced concrete frames to avoid designing for torsion.
A3D MAX plastic analysis features provide the following results for steelwork and other structures:
- Load factor at which the first
- Plastic hinge forms for each load combination
- Full history of plastic hinge formation up to collapse for selected combinations
- Bending moment and other results for any member at any stage up to collapse
A3D MAX provides user friendly access to the full elastic-plastic P-Delta analysis functionality previously only available in much more cumbersome and expensive software. Users may elect to include or ignore P-Delta effects in elastic or plastic analysis.
Elastic Critical Load Factor (λcr) Determination
In recent years the ‘elastic critical load factor’ has become an important parameter for determining the sensitivity of frames to second order buckling effects. A3D MAX provides an independent analysis feature to automatically determine Lambda crit for selected
load combinations by incremental second order elastic analysis. The load factor of the lowest buckling mode is detected. For unbraced frames this will be a sway mode and for braced frames a non-sway failure of the frame or a critical member will govern.
A3D MAX enables users to define supports as ‘lift-off’ in their structural models, enabling the condition to be detected and designed for more easily and safely. This is especially valuable in more complex structures where ‘lift-off’ may not be anticipated by simple inspection.
Tension / Compression-only Members
A3D MAX includes functionality that enables users to define members as tension / compression- only elements in their structural models, so that they can be designed and checked accordingly.
A3D MAX provides functionality to model the rigidity of practical steelwork connections enabling the benefits of semi-rigid connections
to be exploited as well as the usual rigid and pinned options.
When necessary, A3D MAX is able to carry out incremental elastic-plastic analysis of structures containing tension-only members and
lift-off supports. Similarly, elastic critical load determination can take account of directional members and lift-off supports.
Panel Loading and Rigidity
A3D MAX panel feature is a productivity aid which allows single panels or whole floors or walls to be loaded with uniform, patch, point and line loads which the program automatically applies to the supporting beams or columns, thus saving the user huge amounts of time all without the need for FE plate analysis. Floors and groups of panels may be defined as rigid plates to model the diaphragm action of most concrete floor systems.
