Graitec releases version 2022 of Advance Design

June 2021 – GRAITEC is delighted to announce that Advance Design 2022 has been released. Based on the needs and requests of the ever-growing communities that have gathered around each software developed by Graitec, we have developed exciting new features to enhance all your structural projects.

GRAITEC Advance Design Release 2022

Advance Design 2022, the leading structural analysis software, is enhanced with a lot of new functionalities with high benefits for the end user, and is articulated around several main subjects:

We are inviting you to take a look at the selected new features and improvements brought to Advance Design 2022.

 

Crane moving loads generation

The latest 2022 version of Advance Design now includes the addition of a new crane load generator for moving loads.  This new generator uses a set of special load cases with successive vehicle positions to generate loads from bridge or mono cranes.

These loads are defined along the path (the crane runway) while values can be defined manually by imputing wheel loads or can be generated automatically, according to a crane specification and a code (including rules according to EN 1991-3 and ASCE). It is possible to define and analyze multiple cranes operating simultaneously, either on the same route or different ones.

Together with the load case generation, sets of force envelopes from all force positions are also generated. The final load combinations are defined by using typical load cases (dead, live, wind…) and Crane Envelopes.

 

The static calculation and the results for the combination cases do not differ from other load types and the user can check the results for each crane position as well as for the envelope of the crane forces. Specific to the crane is a new type of graphical output - the influence line plot. The influence diagram shows graphically the value of the result at a given point for all successive positions of the crane. This influence diagram can be displayed from the postprocessing ribbon.

Improvements on the Pushover Method

The Pushover analysis, available on Advance Design since version 2021, has been extended with the performance point calculation. The performance point is the balance point between the structural capacity, represented by the pushover curve, and the seismic demand, represented by the acceleration response spectrum of ground motions (demand curve). Advance Design 2022 transforms the seismic spectrum into an ADRS (Acceleration Displacement Response Spectra) spectrum according to EC8 or ATC40 and superpose this one with the capacity curve to define the performance point. Those two curves are expressed in the ADRS form and superposed to see graphically the performance point. The corresponding diagram is available from the pushover results curves.

Link on node

Starting with Advance Design 2022 a new link type is available: Node link. It is defined on the intersection point of linear elements and allows for defining relations between selected degrees of freedom on linear elements at this point. There are many possible uses for this type of link, and it is especially useful when modelling scissor connections between two linear elements or a hinged connection between a continuous purlin and rafters. In the properties of a new link type, we can specify its parameters, starting with the coordinate system (global or local) used for a definition. For the local coordinate system, the local system of the primary element is considered. Next, we can select for each degree of freedom the method of connection between elements at a point: rigid, elastic, or free.

Cold formed section design

Advance Design 2022 introduces design rules for cold-formed members, as per EN1993-1-3 and EN1993-1-5. Cold-formed steel profiles are made by rolling or pressing thin gauges of steel sheets and develop both as the main and secondary bearing element. There are many possible applications for cold-formed steel profiles, among others as eaves beams, wall studs, floor joists, frame beams or roof purlins.

Results are available graphically or as sheets per member including gross area calculation, local bow imperfections, distortional buckling (§5.5 from EN1993-1-3), torsion effects due to eccentric loading (§6.1.6 from EN1993-1-3), warping effects (using 7dofs objects), deflection checks (§7.1 from EN1993-1-3)…

New RC slab module

With Advance Design 2022, concrete slabs can now be designed within the new RC Slab module. This new RC Slab module brings a wealth of new features. There is the possibility to generate the theoretical reinforcement using the strip method, the ability to generate the real reinforcement based on the theoretical reinforcement and the added option of generating reinforcement drawings and documentation.

Data such as the slab geometry, supporting systems for beams, columns and walls are transferred across from the main global FEM model and into to the RC Slab Module. However, since the analytical model for FEM calculations may be slightly different from the real geometry, RC Slab provides several options to adjust the imported model, including the outer contour of the slab.

The user can apply the strip method to determine the theoretical reinforcement based on internal forces from the main model. This is a multistage method, where the first step involves the theoretical division of a plate into a number of strips. Each strip is treated individually before the resultant forces over a certain area are integrated. From this, one can then obtain force diagrams along the strip axis. On this basis, the theoretical reinforcement is determined for each strip and finally the real reinforcement.

After the determination of the real reinforcement, the user has the possibility to generate documentation, including drawings. By default, the drawings are generated with a top view for the top and bottom reinforcement, although it is also possible to generate a projection with both surfaces of the reinforcement at the same time.  The user can also influence a number of other parameters such as the number of visible rebars, description types, scale and more.

Enhanced calculation capabilities in RC modules

New methods for the determination of the bar distribution of the longitudinal reinforcement have been added to the Beams and Columns module. In both cases, the previous methods were based on a pre-set number or spacing of the members, whereas the new methods allow for an automatic selection of the number of reinforcing bars starting from the smallest number of bars and increasing their diameter step by step. By briefly comparing the two methods now available, we can now decide whether for the same required theoretical reinforcement area we want fewer bars with a larger diameter or more bars with a smaller diameter.

A new soil bearing capacity method called the Substitute foundation method was added to the analysis of foundations located on multi-layered soil. The idea behind this method is to check the bearing capacity of each soil layer separately – starting from the foundation level, but then for the next layer the check is done at its top level. For this, it is assumed, that there is a fictitious foundation located on the top level of this layer, with a bigger width and forces that result in a different stress distribution and bearing capacity. This method is especially useful when some of the next layers are weaker than the above layers.

Increased capability of 3D reinforcement generation

The latest version of the program has introduced many improvements in the generation and editing of 3D reinforcement in the reinforced concrete modules. One of those is the completely modified part concerning the editing of transverse reinforcement in columns. Thanks to the editing in the table, the linking of the reinforcement packages as well as the easy selection of the distribution type, the editing or generation of the transverse reinforcement is fast and intuitive.

Another example of an improvement is the easy configuration of and defining of multiple links for beams.  Now the selection of layout configurations for multiple links is very quick and intuitive thanks to special graphical lists showing the available bar layouts for a given number of longitudinal bars.

Faster analysis of steel connections

Starting with the 2022 version all connection available in the Steel Connection module can be designed either using all combinations or by using automatically determined combination envelopes. In this case, the connection is analyzed only for combinations that satisfy a number of envelope criteria ensuring that all combinations giving minimum/maximum forces for individual verifications are selected. As a result, the calculation time for more combinations is reduced greatly.

New synchronization mechanism

The dialog window used during the synchronization of data using Graitec GTCX format has been modified. This makes the process of synchronizing models much easier and faster. With new options, the user has more control over the synchronized data. Among the many improvements and new features, we can mention the ability to easily filter data, easy table configuration, clearer presentation of status and changes, and a tree-based data structure. In addition, it has been made possible to select the range of results imported into Autodesk Revit.

Miscellaneous improvements

This version 2022 of Advance Design also comes with a big number of improvements and adjustments following the feedback received from thousands of users worldwide. Here is an extract from the ’00s of new features implemented in this new version.

New options for quick changes of settings for diagrams: to facilitate the daily work while viewing the results of FEM calculations by providing quick access to frequently used commands, two new icons have been added to the Result ribbon to manage the load's cases selection and the envelopes definition.

GRAITEC Advance Design 2022 - MISCELLANEOUS IMPROVEMENTS
GRAITEC Advance Design 2022 - save results color scale

Possibility to save results color scale: to easily use own color scale of results, Advance Design 2022 gives the possibility to save the current definition of scale settings. The saved colors definitions can be shared between different projects!

Also, the user has now the possibility to increase the number of zones of colors beyond the previous limit of 16 colors up to 50.

Stresses for supports available from the ribbon: in the list of FEM results available for supports in the Results ribbon, the user can now select also stresses. This change makes it possible to display stress results for both linear and surface supports.

GRAITEC Advance Design 2022 - Work ratios for strength

Additional Work ratios for strength: In the Advance Design 2022 version, the process of exposing more details about the results of steel profile analysis continues. With this, several additional results are available in the graphical results list for strength analysis from ongoing verifications for combined sets of forces.

Automatic generation of generic connections on selection: when defining generic connection on a selection now connections are generated separately on each node/intersection of selected linear elements. It also covers a selection of punctual supports, as now generic joints can be generated also between punctual supports and linear elements. This upgrade greatly increases the speed of the definition of generic connections in the structure.

GRAITEC Advance Design 2022 - Modelling Shear plate connections

Modelling Shear plate connections: Advance Design 2022 allows the definition shear plate connections. New connections are created by using new commands that can be found on the Connection panel on the Objects ribbon:

  •   Beam to beam web
  •   Two beams to beam web
  •   Beam to column flange
  •   Beam to column web
  •   Two beams to column web

Transfer of super element to RC Beam module: Starting from the Advance Design 2022, it is possible to transfer a multi-span RC beam modeled from single spans to the RC Beam module. To do this, it is enough to create a super element with these spans earlier. This solution has many advantages, including both the ease of creation and the possibility of treating the beam as continuous, with different parameters for individual spans (e.g. section height).

GRAITEC Advance Design 2022 - Schedules for reinforcement fabrics

Schedules for reinforcement fabrics: In the module for reinforced concrete walls as well as in the new module for reinforced concrete slabs it is now possible to generate schedules for reinforcement fabrics. This schedule contains information about the used meshes and cuts and can be added to the drawing separately or together with the reinforcement schedule for bars.
