Useful Program Features
Dlubal Software programs and add-on modules include a wide range of powerful features.
Since our software is subject to continuous development, we are constantly adding new features. In doing so, we also take account of our customers' wishes.
Why Dlubal Software?
Calculation of stiffened buckling panels according to EN 1993-1-5, 4.5In SHAPE-THIN 8, the effective cross-section of stiffened buckling panels can be calculated according to EN 1993-1-5, Cl. 4.5. The critical buckling stress is calculated according to EN 1993-1-5, Annex A.1 for buckling panels with at least 3 longitudinal stiffeners or according to EN 1993-1-5, Annex A.2 for buckling panels with one or two stiffeners in the compression zone. The design for torsional buckling safety is also performed.
RF-MOVE Surfaces | Generation / Results
You can create various load cases with a single mouse click. After the generation, the numbers of the created load cases and result combinations are displayed.
The RF-MOVE Surfaces add-on module does not display any result windows. You can check the created load cases including loads in RFEM.
Descriptions of the individual moving loads are created on the basis of the respective load step number. However, it is possible to edit the descriptions in RFEM.
You can export all data in tables to MS Excel.
RF-MOVE Surfaces | Input
Surfaces with moving loads are selected graphically in the RFEM model. You can apply loads with several different sets of movement on one surface at the same time.
The "lane" is defined by sets of lines. You can select them graphically in the model. In addition, you can enter the increment of the individual load steps. Several load types are available, for example single, linear, rectangular, circular, and various axle loads. They can be applied in local and in global directions.
The different loads are summarized in load models. The module assigns defined load models to the sets of lines and creates individual load cases based on this data.
RF-INFLUENCE | Input
Member and surface models created in RFEM are analyzed at a particular point by applying a unit load with the previously defined load magnitude and direction. The module determines the way of unit load effects on the internal forces for the inspected point.
This simulation is represented graphically by an influence line or influence surface resulting from the load magnitude of the force or moment on the inspected model point. The graphical representation can be used for further analyses or to check the behavior of the model.
The RF-INFLUENCE add-on module determines the influence lines and surfaces of models containing beams and surfaces.
RF-INFLUENCE | Calculation
After defining the points to be analyzed, the module generates influence lines and surfaces. Then, all result diagrams are available in result windows sorted by points and unit loads applied on members, surfaces, and supports.
RF-INFLUENCE | Results and Export
The results of each influence line and surface are listed in result windows. However, it is also possible to evaluate them graphically.
You can export the result tables to MS Excel. In addition, the global RFEM printout report is available for printing the input and result data as well as graphics.
RF-/STAGES | Features
- Simple definition of construction stages in the RFEM/RSTAB structure including visualization
- Addition, removal, and modification of member, surface and solid properties (such as member end releases, surface eccentricities, degrees of freedom for supports, and others)
- Optional superposition of construction stages with additional temporary loads, for example mounting loads or mounting cranes, and others
- Consideration of nonlinear effects such as failure of a tension member, elastic foundations, or nonlinear supports
- Numerical and graphical result display for individual construction stages or as an envelope (Max/Min) of all construction stages
- Detailed printout report including all structural and load data of each construction stage
RF-/STAGES | Entering Construction Stages
After creating the entire structure in RFEM/RSTAB, the individual structural components as well as load cases and combinations are assigned to the corresponding construction stages. For each construction stage, you can modify for example release definitions of members and supports.
Thus, it is possible to model structural modifications, as they occur by successive grouting of bridge girders or by settling of columns. The RFEM/RSTAB load cases and combinations are assigned to "Permanent Loads" and "Temporary Loads".
The defined temporary loads are superimposed by permanent loads. In this way, it is possible to determine the maximum internal forces of different crane positions or to consider temporary mounting loads available only in one construction stage.
RF-/STAGES | Calculation
The calculation of the "Permanent Loads" is performed in compliance with the large deformation analysis successively for each construction stage.
Resulting geometry differences between the ideal and the deformed structural system from the previous construction stage are compared in the background. The next construction stage is based on the structural system stressed from the previous construction stage.
RF-/STAGES | Results and Export
After the calculation, it is possible to evaluate the results of each construction stage directly in the module window or graphically in the RFEM/RSTAB model. In this case, you can export the results to RFEM/RSTAB.
The module creates result cases of each construction stage as well as an enveloping "combination" including the maximum and minimum values of all construction stages. You can use the result cases and the enveloping combination for further calculations in various RFEM/RSTAB add-on modules.
