Stress Relieving Structural Steel
Stress Relieving Structural Steel
(OP)
Hi
I am designing a steel structure that will be a welded construction using hot rolled square hollow section steel to BS EN 10025 S275JOH.
I need to know the following:
1) What is a suitable stress relieving process?
2) Will the stess relieving have any effect on the strength of the stucture?
(apologies, this request has also been posted in the Metal and Metalury Engineering section, wasnt sure which section was best)

RE: Stress Relieving Structural Steel
Something to consider when stress reliveing is that your structure may distort after the process.
Is your particular steel quenched & tempered? (I'm not familiar with UK steel types). If its Q&T, you don't want to use thermal stress relieving.
Can you elaborate some more on your particular application?

Ciao.

I would think you DO get a benefit from stress relieving for static structures- it is required in cases where loading is not considered cyclic.
RE: Stress Relieving Structural Steel
I am really trying to gauge whether stress relieving is required and if so what is a suitable process?
Thanks

RE: Stress Relieving Structural Steel
An effective vibration treatment can be performed by documenting the resonance pattern prior to treatment, and monitoring changes to the resonance pattern (chiefly growth of the resonance peaks, often accompanied by minimal shifting of the resonance peaks to lower frequencies). These changes will be quick in the beginning of the treatment, but subside as stability is approached.
