  • Answer

    When modeling stiffeners (ribs), there are some things to consider.
    I attached a test model to you in the attachment of the mail.
    For flat surfaces, it is generally the case that objects lying in the surface (ie lines and nodes)
    automatically integrated into the surface. For curved surfaces this must be done manually.
    Accordingly, I have manually removed the line in the left model from the surface (see picture).
    As a result, the line is connected to the surface only at the nodes.
    For the following models 2 and 3, the lines are already automatically integrated into the surfaces.
    This means that the rod is rigidly connected to the surface over its entire length.
    The 4th model is modeled using surfaces and provides the same results as far as possible
    as with bars. As a rod type "rib" I would not define the stiffeners as this
    are primarily reserved for the design of reinforced concrete (design as a slab beam).

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. ”
