Creep of Steel at Elevated Temperatures
Complete stress-strain curve
The full stress-strain curve includes incremental part, constant stress and descending part
Dear Mr. Abolfazl Yousefpoor ,
In my opinion you can go with TMT (Thermo Mechanically Treated) Rod steel used often in RCC buildings which will be subjected to creep during fire catch to building.
You can see my publication " effect of elevated temperature on some properties of air entrained steel fiber concrete"
Hi I am trying to perform an optimization using GA and for that I need to use the ansys and matlab. how to I link ansys and matlab? Does anyone have this software( Ansys aaS Matlab toolbox)?
