  • Answer

    An overpressed joint between two members can be controlled in RFEM by means of the member stress results. For members, this stress result represents the effective stress as a color gradient across the member surface depending on the assigned cross-section.

    Figure 01 - Stresses on Members

    Based on the local member axis, the member stress result gives the following stress components and reference stresses with an associated color palette:

    • Stress
      • σx
      • τy
      • τz
    • Elastic stress component
      • σN
      • σMy
      • σMz
      • σN+My
      • σN+Mz
      • σM
    • Elastic equivalent stresses
      • σv,Mises
      • σv,Tresce
      • σv,Rankine
      • σv,Tresca+Rankine
      • σv,Bach

    Using active displaying for the members connected to the joint, and displaying the σx stresses, it is possible to visualize the state of stress on and thus also between the members. If only negative stresses occur in the area between the members, the joint is overpressed.

First Steps

First steps

We provide hints and tips to help you get started with the main programs RFEM and RSTAB.

Wind Simulation & Wind Load Generation

With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

Your support is by far the best

“Thank you for the valuable information.

I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
