Type 2D – XZ is preferred for planar frames since this option only takes into account moments about the strong member’s axes. The RFEM library of materials contains many types of concrete, metals, timber, glass, and foil as well as gas and soil. RFEM creates either Load or Result combinations during automatic superpositioning. Chapters 5.5 & 5.6 explain the differences between these combination options. This list gives you the option to choose from different National Annexes. The European Commission recommends that the CEN option be selected. RF/FOUNDATION Pro allows the user to select the percentage of soil pressure that is being relieved by using the factor kred.

RFEM, a powerful 3D FEA software program that helps structural engineers meet modern civil engineering requirements, is a strong tool. RFEM is easy to use thanks to its intuitive interface, user-friendliness, and efficient data input. To add a brief description to the general data, you can either type in text or choose from the list.
RFEM is a program that allows for the structural analysis, dynamic analysis, and design of 3D structures. This dialog section controls the orientation of Z’s global axis. The Z-axis in CAD programs is normally directed upwards, while structural analysis programs are usually directed downwards. You can adjust the combination coefficients and partial safety factors of the current standard by pressing the button. RFEM can provide deformations, soil contact stresses, and internal and support forces. The data input can be further enhanced by adding-on modules that automatically create connections and structures, and carry out analyses and design work. The main program RFEM can be used to create structures, materials, and loads for spatial and planar structural systems that include plates, walls, shells, members, and other elements.

RFEM can automatically create load and result combinations by providing load cases with the correct combination coefficients and partial safety factors. The options below can’t be accessed if this box is not cleared. If this happens, you will need to manually create the load and result combinations (see Chapter 5.5.1 & Chapter 5.6.1). The specified standard allows partial safety and combination factors automatically to be assigned. RFEM provides many interfaces that allow data to be exchanged within BIM processes. Digitally storing all relevant building data within a 3-dimensional model is a key to all planning stages. The same model is used by all CAD and structural analysis programs. This allows for seamless transfer between them.

The rules for creating load- and result combinations in RFEM can be defined by selecting the standard. This specification is important for the automatic creation of combinations (see Chapters 5.2 and 5.4). Selecting the checkbox in the New Model-General Data dialog box will allow you to select the template model that you want from the list. Click the button to define surface and member settings if the Z-axis points upwards. You will find the factors organized in the Coefficients dialog. The first tab displays the Partial Safety Coefficients (g) for design situations such as “static equilibrium” or “ultimate state”.

You can choose the folder where the model will be created from the Project Name List. You can make any changes to this presetting by accessing the dialog button at the right. It is shown in the printed report, but it has no other relevance, just as the project description.
Load cases must be manually superimposed in this instance (see Chapter 5.5.1 & Chapter 5.6.1). Cross-sections in RFEM’s cross library include rolled, built up, thin-walled and thick-walled sections for steel, concrete, and timber. Save as Template dialog boxThe templates are generally stored in the Dlubal folder called Base.
Modularity allows you to mix and match programs according to your requirements. RFEM offers many interfaces that allow for seamless interaction between CAD, structural analysis, and Building Information Modeling.
Next, answer the query shown in Figure 12.29. This will appear when you close the General Data dialog box. You will need to indicate whether your structure is a planar or spatial model in the general data section. The input effort required for 2D models is lower due to the limitations of coordinates and degrees. The structural engineering program RFEM allows you to quickly model and calculate 3D as well as 2D structures. These include member, plate, shell, wall, shell, and solid elements. Retroactively changing the standard requires you to reclassify load cases and adjust your combination. If None is selected, no combinations will be created automatically.
RFEM, a 3D finite element analysis software that runs under Microsoft Windows operating systems, is a 3D finite-element analysis software. This video explains the basic interface and the FEA structural analysis software RFEM workflow in five minutes. Each standard specifies rules for how to combine load cases. It is important that load cases are assigned to specific action categories (see Chapter 5.1.1).
Why is there a discontinuous area of distribution of internal forces in my area? The sheer force VEd is showing a jump in the area around the supported line. This does not seem to be possible.
It is possible to create combined structures and also model solid and contacts elements. You can also create combinations automatically. Additional dialog tabs are available in the Edit Load Cases & Combinations dialog box. Separate entries in the Data navigator and Tables 2.2 are also available. Chapters 5.2 through 5.4 describe how to create combinations.
