Hot sustained and Hot Elastic Modulus - 09/13/17 07:53 AM
Hi,
I´m doing a stress analysis @ 1000 °F. I´m using Hot elastic modulus for loads and cold elastic modulus for stress. My question is about "hot sustained". When I use hot elastic modulus the pipe is not lifting up and I don´t have problems with hot sustained case. But If i use cold elastic modulus the pipe is lifting up, so I have problems with hot sustained stresses. According to the codes I shall use cold modulus for stress, but I´m not sure how to deal with hot sustained in my case.
