How can I consider a sway bracing in CRANEWAY?

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)
Note:
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.
