Design / material

Automatic design of the plate as well as the beams when using re-inforced concrete

If you do not perform a design, you can define any orthotropic material

Data transfer to the applications DLT for the beam design and B6+ for the punching shear analysis of columns

Area definitions

Supporting direction areas for the definition of uniaxial supporting areas

Bedding areas for elastic bedding, you can optionally define bedding failure

Reinforcement areas for the defi-nition of a basic reinforcement and the setting of rotated rein-forcement directions by default

Thickness areas to describe partial plate areas with different thick-nesses

Supports

Point or line supports are generated via the objects column and wall, whereby the application automati-cally calculates the real rigidity val-ues, if the corresponding option was activated. There are several repre-sentation options for the bearing re-actions at walls, either in the form of various diagrams in kN per linear metre or in the form of points along the wall axis.

You can optionally include tension spring failure for columns and walls in the calculation.

Loads

You can define single, line, distrib-uted and temperature loads in any layout.

Mesh generator

The automatic mesh generator al-lows you to generate meshes with triangular and rectangular elements as well as mixed meshes.

FE analysis

The plate elements include dis-placement and stress approaches. A considerable benefit of these so-called hybrid elements is their accu-racy with thin plates that are fre-quently used in building construc-tion. Alternatively, elements in ac-cordance with the Reissner-Mindlin theorem are used for thick plates. They include the shear deforma-tions.

Superposition

The PLT application includes a fully automatic superposition feature that takes the selected regulation into account. The user can exclude particular load cases from the su-perposition.

Each load case is assigned to a group of actions. On the basis of this as-signment, the application calculates the decisive load combination in-cluding a corresponding leading ac-tion.

You can optionally perform the cal-culation with alternative load cases.

T-beams

T-beams are considered by adding the rigidity terms along the beam axis. Since the plate elements do not include normal forces, the gravity axis of the beam elements is as-sumed to lie in the plate plane. The rigidities are calculated using Steiner portions. The beam rigidity can be increased by entering a factor.

Bending design of reinforced con-crete

The design of the reinforcement is performed in accordance with the Baumann method. A cracked plate element is used as a model. The de-sign approach assumes an orthogo-nal mesh reinforcement. The rein-forcement direction is freely defin-able.

Shear design of reinforced concrete

The shear design is based on a bar structure model whereby the longi-tudinal reinforcement is taken into account. You can define by default any longitudinal reinforcement over the total plate outline to accelerate the analysis. The results reveal quickly where shear reinforcement can be avoided by increasing the longitudinal reinforcement.

Representation of the results

All results are shown at any grid point or along sections independ-ently of the generated element mesh. The section representation also includes an overview of all re-sults at a particular section.

You can also display the results in the form of ISO lines.

Reinforcement data transfer

Reinforcement data are transferred in an open data format referred to as ASF. The use of these data in the target system is independent of the available system functions.

FEM results transfer

The ASF format allows the transfer of all data produced in the FEM cal-culation. These data provide for the visualization of all results in the CAD system ALLPLAN.

SCN

Panels by finite elements

The SCN application is suitable for the calculation of any load-bearing panel structure or wall-type girder in accordance with the finite ele-ments method.

SCN uses the well-known high-performance graphic operating elements of the GEO and PLT applications. Numerous functions allow the fast and efficient han-dling of complex geometries.

Supports

The objects of the interactive user interface allow you to generate point or line supports directly. There are several representation options for the bearing reactions of the line supports, either in the form of various diagrams in kN per linear metre or in the form of points along the support axis.

Loads

For the definition of loads you can select among point and trapezoi-dal loads in any arrangement.

Superposition

The SCN application includes a fully automatic superposition feature that takes the selected regulation into account. The user

can exclude particular load cases from superposition.

Each load case is assigned to a group of actions in combination with any standard. On the basis of this assignment, the application calculates the decisive load com-binations including the corre-sponding leading action.

You can perform the calculation using alternative load cases.

Design The design of the reinforcement is performed in accordance with the Baumann method. A cracked panel element is used as a model. The design approach assumes an orthogonal mesh reinforcement.

Mesh generator

The automatic mesh generator allows you to generate meshes with triangular and rectangular elements as well as mixed meshes.

Representation of the results

All results can be displayed at any grid point or along sections inde-pendent of the generated element mesh. Section results can be shown in a separate window as well as in the ground plan.

You can also display the results in the form of isolines.

Reinforcement data transfer

Reinforcement data are trans-ferred in an open data format referred to as ASF. The use of these data in the target system is independent of the available sys-tem functions.

FEM results transfer

The ASF format allows the transfer of all data produced in the FEM calculation. These data allow the visualisation of all results in the CAD system ALLPLAN.
