Calculation of Critical Buckling Stress in PLATE-BUCKLING for Column Buckling Behavior

I am using the PLATE‑BUCKLING add-on module and need more detailed information on how the critical buckling stress for the column buckling behavior is calculated. The stiffeners end before the edges. Is the eigenvalue of the stiffener calculated as a member with the effective slab width?

Answer:

If your buckling stiffeners are not defined via the complete buckling length, the PLATE‑BUCKLING program will automatically generate this stiffness as a result member, including the effective width, and the eigenvalue calculation is performed using the BUCKLING add-on module. This then results in the critical buckling stress of the member, and thus, of the stiffener. The length of the equivalent member is the stiffener length. Currently, it is not possible to display the internal results in detail.

Masonry Residential Building
The properties of the connection between a reinforced concrete slab and a masonry wall can be correctly considered in the modeling using a special line hinge that is available in RFEM 6. This article will show you how to define this type of hinge using a practical example.
Activation of Standards for Load Wizards
The effects due to snow load are described in the American standard ASCE/SEI 7-16 and in Eurocode 1, Parts 1 through 3. These standards are implemented in the new RFEM 6 program and the Snow Load Wizard, which serves to facilitate the application of snow loads. In addition to this, the most recent generation of the program allows the construction site to be specified on a digital map, thus allowing the snow load zone to be imported automatically. These data are, in turn, used by the Load Wizard to simulate the effects due to the snow load.
Illustration of a method for performing stability analysis according to DIN EN 1992-1-1 in RFEM 6
For reinforced concrete components and structures with structural behavior considerably influenced by the effects of the second-order analysis, Eurocode 2 provides the general method based on a nonlinear determination of internal forces according to the second-order analysis (5.8.6), as well as the approximation method based on the nominal curvature (5.8.8).

The aim of this technical article is to perform a design according to the general design method of Eurocode 2, using the example of a slender reinforced concrete column.

Product Features
Feature 002443 | Control of Crack Condition for Deformation and Crack Width Analysis

Various design parameters of the cross-sections can be adjusted in the serviceability limit state configuration. The applied cross-section condition for the deformation and crack width analysis can be controlled there.

For this, the following settings can be activated:

  • Crack state calculated from associated load
  • Crack state determined as an envelope from all SLS design situations
  • Cracked state of cross-section - independent of load
Feature 002415 | Improved Segmentation for Deformation Analysis

In the "Deflection and Design Support" tab under "Edit Member", the members can be clearly segmented using optimized input windows. Depending on the supports, the deformation limits for cantilever beams or single-span beams are used automatically.

By defining the design support in the corresponding direction at the member start, member end, and intermediate nodes, the program automatically recognizes the segments and segment lengths to which the allowable deformation is related. It also automatically detects whether it is a beam or a cantilever due to the defined design supports. The manual assignment, as in the previous versions (RFEM 5), is no longer necessary.

The "User-Defined Lengths" option allows you to modify the reference lengths in the table. The corresponding segment length is always used by default. If the reference length deviates from the segment length (for example, in the case of curved members), it can be adjusted.

Feature 002416 | Result Display via Clipping Plane

This feature also contributes to the clearly-arranged display of your results. Clipping planes are intersecting planes that you can place freely throughout the model. The zone in front of or behind the plane is consequently hidden in the display. This way, you can clearly and simply show the results in an intersection or a solid, for example.

Feature 002423 | Displaying Results in Solids

The results of solid stresses can be displayed as colored 3D points in the finite elements.
