The RF-MOVE/RSMOVE add-on module does not display any result windows: You can check the created load cases, including loads, in RFEM/RSTAB. Descriptions of the individual moving loads are created on the basis of the respective load increment number.
However, it is possible to modify the descriptions in RFEM/RSTAB. You can export all data in tables to MS Excel.
You can create various load cases with a single mouse click. After the generation, the numbers of created load cases and result combinations are displayed.
Sets of members with moving loads are selected graphically in the RFEM/RSTAB model. You can apply several different types of loads to one set of members at the same time.
By specifying the first load position, you can precisely display the load entering the runway of the continuous member. In the same way, it is possible to define whether a moving load consisting of various load applications is allowed to move beyond the end of continuous members (bridge) or not (crane runway).
The increment of the individual load positions is determined by the number of load cases generated for RFEM/RSTAB. You can also add loads to already existing RFEM/RSTAB load cases so that no additional superposition is required. Several load types are available, for example single, linear and trapezoidal loads as well as load pairs and several uniform concentrated loads.
It is possible to apply the loads in local and global directions. The application can refer to the true member length or to the projection in a global direction.
In 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.
You can create various load cases with a single mouse click. After the generation, the numbers of created load cases and result combinations are displayed.
The RF-MOVE Surfaces add-on module does not have 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.
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 'envelope' 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.
The calculation of the "Permanent Loads" is performed in compliance with the large deformation analysis successively for each construction stage.
The 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 built on top of the stressed system from the previous construction stage.
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, such as those that occur when bridge girders are successively grouted or when columns are settled. The load cases and load combinations already created in RFEM/RSTAB are divided into "Permanent Loading" and "Temporary Loading" in the add-on module.
The defined temporary loads are superimposed by permanent loads. 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.

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.
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 the unit load affects the internal forces at 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 at 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.
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 means of line sets. 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 these data.
The results of each influence line and surface are listed in result windows and 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.
