Dear All

During a FRP calculation based on ISO 14692, I noticed that reducers are not evaluated (Caesar II 2017).

The end node of the pipe gives an occurring stress and an allowable stress. The corresponding start node of the reducer gives an occurring stress but no allowable stress. Again the end node of the reducer gives occurring stress but no allowable stress. The start node of the connecting pipe gives an occurring stress and an allowable stress.

I have studied the ISO, but I can’t find a remark that reducers should not be calculated. It is also remarkable that in Caesar a SIF factor has been determined and applied to the occurring stress but does not perform an evaluation of these values.

Am I doing something wrong, or is it correct that Caesar does not evaluate reducers based on ISO 14692?

Thanks for the help!
