We are inviting you to take a quick look at the selected new features and improvements brought to the Advance Design 2020.
New FEM calculations capabilities
Advance Design 2020 introduces new functionalities that significantly enhance seismic analysis capabilities.
A new solver method is available for modal analysis: Load-dependent RITZ vectors. Ritz vector analysis is better adapted for Seismic and Spectral calculations, because it manages to compute only the vibration modes that are significantly excited by the loading (discarding modes with low participation factor). In addition, it allows for automatic determination of number of modes according to a user target participation ratio. Thanks to these features, while maintaining the same level of accuracy, it is possible to significantly reduce the time spent on seismic analysis.
Advance Design 2020 introduces also a new tool to assess the seismic performance of buildings, by inputting ground motion records and performing a time-history analysis. Thanks to a possibility for selecting accelerograms as solicitation type for time-history analysis, it is possible for predicting building behavior on a given location and for various ground motion intensities.
Climatic generator improvements
Starting with Advance Design 2020 it is possible for automatic generation of wind loads on lattice open structures, according to provisions from the American ASCE 7-10 code. Implemented method is usable for any kind of open structures, like pipe racks, industrial/petrochemical structures and trusses. Can be also used for lattice masts, like transmission towers or lattice telecom towers.
The newest Advance Design version supports new building geometries for automatic wind load generation according to Eurocode 1 by a consideration of CNC2M recommendations. The CNC2M French committee established a set of rules to complement EN1991-1-4 with information regarding more complex geometries. Accordingly, new rules have been implemented in Advance Design to enable automatic generation of wind loads for buildings with horizontal setbacks (L shape), buildings with awnings and improved rules for monopitch canopy roofs.
New possibilities for the Steel Design
Advance Design 2020 introduces a set of improvements significantly facilitating the definition of intermediate restraints for steel linear elements, used for reducing lateral-torsional buckling according to the Eurocode 3. It is now possible to very quickly and easily define restraints directly on a 3D model using several methods, as well as to check their location thanks to a possibility for displaying symbols of restraints in a model. The Lateral-torsional buckling dialog has been significantly expanded and introduces new methods of restraints definition, a greater control thanks to a new graphical preview and allows for a direct input of the critical moment.
Advance Design 2020 offers the possibility to use any section shape available in Graitec Profile library, in the Steel Design with the Advanced Stability solver. The Advanced Stability ensures a thorough analysis of individual members by performing a 2nd order calculation with lateral-torsional buckling with imperfections and warping effects. By allowing the Advanced Stability analysis on any section from the Graitec Profiles library, Advance Design 2020 enables the verification of any cross-section shape, even mono symmetric or asymmetric shapes which are widely used in practice but not covered by design rules.
The new version of Advance Design introduces also several improvements in the search process for optimal steel profiles. The user control over the range of profiles to be searched is enhanced by a possibility for determining geometric limits. The user has also gained control over the search criteria through the possibility to choose the method (by weight, by height, by width or by inertia). This is particularly useful in the case of optimizing profiles whose sorting against various parameters gives different results (for example, in the case of pipes or W sections).
Advance Design 2020 allows definition a new HSS Bracing connection type. This new gusset plate joint can be modelled with one, two or three diagonals of round or rectangular tubes. The HSS Bracing connection can be configured in detail and verified according to the Eurocode provisions using the built-in Advance BIM Designers Steel Connection module.
Design of RC Walls
Advance Design 2020 enables detailed analysis and generation of reinforcement for concrete walls thanks to a new Advance BIM Designers Reinforcement Wall module.
The RC Wall module calculates the reinforcement depending on loads and makes the necessary verification according to international codes for two types of walls: Bearing walls (with gravitational loads) and Shear walls (placed into seism zones). Walls can be analyzed individually or in a group. The result of the calculation is a reinforcement area made of bars or fabrics, depending on users’ needs.
Improvements to modeling and presenting results
The newest version of the Advance Design brings a lot of new features and improvements that accelerate modeling and facilitate analysis of results. Let's look at some of the chosen ones:
The tool for defining Grid axes has been extended to enable full control of the axis naming. It is possible now to use prefixes (any text) with automatic naming of axis. In addition, the name of each axis can now be changed as required.
Advance Design 2020 allows for full control over the structure analyzing using cracked sections of the concrete linear elements by giving a possibility for defining effective stiffness coefficients separate for 4 stiffnesses (axial, torsional, bending in the strong and in the week axis).
The manual reduction of the stiffness of the element in a given direction may be useful for modelling the different behaviors of the element. The reduction of the section's moments of inertia allows for considering section cracking of the concrete elements in static calculations independently in the chosen direction.
The values of support reactions can be checked much faster and more conveniently thanks to direct access from ribbon, the ability to graphically present multiple reactions at the same time and the possibility to display their descriptions.
With the Advance Design 2020 is much easier to manage and check the status of structural components due to their design calculations. A set of new parameters showing the design calculation status and the maximum work ratio are available on the property list of linear and planar elements, that allows for a quick check of the status of a given element. These parameters can also be used for selection purposes, so that one can quickly select, for example, elements that have not yet been designed or elements within a given work ratio range.
New possibilities for cooperation with other software
To enable a more complete cooperation between Advance Design and CS-Statik modules, a direct link between the two systems has been introduced in version 2020. It is possible to export data from Advance Design from both the descriptive and the analytical model.
For both cases a single CSX file is imported into the Project center of CS-Statik.
In a new version of Advance Design, the export capabilities with using the Graitec BIM format were increased by the export of FEM results for walls and theoretical reinforcement areas for slabs. These results can be imported into Autodesk Revit and then used by the BIM Designers Wall and BIM Designers Slab modules to generate the real reinforcement based on Advance Design analysis results.
