  • Answer

    Entering a sway bracing as a structure is currently not possible in CRANEWAY. However, you can determine the replacement spring in RSTAB or RFEM, which can then be considered as lateral support in CRANEWAY. Proceed as follows:

    1. Model the sway bracing in RSTAB or RFEM
    2. Apply the unit load 1kN at the location of the lateral support
    3. In this way, determine the nodal deformation in global Y for each position of the lateral support.
    4. Calculate the equivalent spring from the determined deformation and the load. (see Figure)
    This method is not recommended in specialized literature. The reason for this is that the spring stiffnesses change for each wheel position and furthermore the RFEM for the crane runway girder in its capacity as truss flange remains unconsidered in the design.

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. ”
