Gerhard Rehm General RFEM RSTAB

In the global calculation parameters, the option "Special treatment" of members is grayed out and can not be activated. What is the reason for this?


This option is only available even if nonlinear structural elements (for ex Tension members) are contained in the structure. You can easily check if this is the case. Open the global calculation parameters and check the "Nonlinearities" dialog box at the bottom left to see if the option "Members due to member type" or the option "Member Nonlinearities" is available. If they are grayed out, there are no members with these parameters and the "Special treatment" option is accordingly unavailable, because then there will be no failing members.
