Tangential Orientation of Members on Curved Members or Singly Curved Surfaces

Tangential Orientation of Members on Curved Members or Singly Curved Surfaces

Gerhard Rehm | Dlubal Software

If you want to connect members tangentially to a curved member or a curved surface in RFEM, it is necessary to define member rotation of the connected members. In order to avoid manual determination, you can display the center point of the curved line and place a node on it. Then, you can select the “Member Rotation via Help node” option and specify the relevant help nodes. Thus, the members are rotated automatically in the defined plane (x-z in our example) and the top edge of the rotated cross-section is parallel to the tangent of the curved line.

Thermally Toughened Glass in RF-GLASS

Thermally Toughened Glass in RF-GLASS

Ulrich Lex | Dlubal Software

According to DIN 18008-1, Chap. 8.3.6, the design value of the load-bearing capacity differentiated to other glass should be applied for thermally toughened glass as follows:
R_d = (k_c x f_k) / Gamma_M

You can activate and deactivate the application of this formula in Table 1.2 under material parameters. The applied formula parameters are available in the Standard dialog box where you can check them and also modify them to some extent.

Design Situation Settings for SLS Checks in RF-CONCRETE Surfaces and RF-CONCRETE Members

Design Situation Settings for SLS Checks in RF-CONCRETE Surfaces and RF-CONCRETE Members

Design Situation Settings for SLS Checks in RF-CONCRETE Surfaces and RF-CONCRETE Members

Adrian Langhammer | Dlubal Software

As of the program version 5.06, RF-CONCRETE Surfaces and RF-CONCRETE Members perform the serviceability limit state designs automatically according to the design situation of the calculated load cases, load combinations and result combinations.

If you want to perform the design for a certain design situation in compliance with a standard and this is not available in the “To Design” column in General Data, a corresponding warning appears after the calculation informing you that the design could not be performed due to missing load.

In this case, you can see the schema of the standard under [Details…] in the “Serviceability” tab and select which design should be performed for the design situation, if necessary. Click the Info button to get detailed information about the individual checks and the corresponding reference to the standard. It is also possible to restore the default values of the standard.

Soil Profile in RF-/FOUNDATION Pro

Soil Profile in RF-/FOUNDATION Pro

Soil Profile in RF-/FOUNDATION Pro

Paul Kieloch | Dlubal Software

As of the program version x.06.1103, it is possible to enter a soil profile in RF-/FOUNDATION Pro. This provides you the advantage to set several soil layers with different soil parameters above and under the foundation base. For entering the soil layers, there is a library with various soils that can also be extended with user-defined soils. The user-defined soil profile is shown in an interactive information graphic. Any change, for example a soil thickness modification, is reflected in the graphic immediately.

In order to enter a soil profile, it is necessary to activate the design for ground failure with the bearing resistance according to EN 1997-1 Annex D, and for sliding. Then, the bearing or sliding resistance is determined using the soil parameters of the defined soil profile and applied for the geotechnical designs.

If you set the allowable soil pressure as user-defined and deactivate the design for sliding in the design details, it is not necessary to define the soil profile anymore. The input dialog box is not available in this case.

“Column” Support Type on Walls

"Column" Support Type on Walls

“Column” Support Type on Walls

Walter Fröhlich | Dlubal Software

RFEM provides an easy way to consider an elastic support of a horizontal slab as a result of connected columns. By specifying column cross-section, column material, column length, and support conditions at the column head and the column base, you can determine support springs and use them in the calculation.

Another advantage of the “Column” support type is that the surface area of the column cross-section is deactivated in the result output. Therefore, singularities are hidden and thus the concrete design applies design cross-sections.

However, if there is an inclined or vertical surface, it is not possible to use this support type without further ado. When trying to perform a calculation, an error message appears pointing out that the surface is not horizontal.

After you define the support as an “elastic node support”, close the dialog box and open the “Edit Nodal Support” dialog box again. Then, you can deactivate the “Column in Z” option. In this case, the determined spring constants are transferred into the “normal” support definition.

It is not possible to apply the “elastic surface foundation” support for inclined/vertical surfaces since the spring constants are not determined until the FE mesh is generated.

If you want to hide the column cross-section also for surface results in the case of inclined surfaces, you can use the average regions for this.

Automatic Load Combination in RF-PIPING

Automatic Load Combination in RF-PIPING

Lukas Sühnel | Dlubal Software

Like in RFEM, automatic combination of load cases is also available in RF-PIPING. This feature is activated by default and creates the required piping and result combinations for design. It is necessary to assign the load cases to the relevant action category. For this, there are new categories implemented specifically for pipeline construction.

After superimposing the thermal load cases with the internal pressure load cases, you get the corresponding combinations. In addition to the automatic load combination, you can also create the other piping and result combinations manually.
