Of course, it is not in a vacuum. I disagree that the rod cannot elongate by itself. A rod sitting on the ground can grow and shrink with thermal changes. But I do agree it cannot hold tension without a support element.
The compression members are masonry which has a much smaller coefficient of...
Thanks! Just want to make sure I understand correctly. Why would the elongation of the rod itself due to thermal expansion from increased temperatures (it is uncovered in unconditioned space) not cause loss in tension? That would be great if it's the case - could you point me to some references?
Hello,
Young engineer here. I have an unconditioned building that I'm reinforcing with tension rods for lateral restraint. I was going to pretension the rods to counteract tension loss from thermal effects and keep the rod engaged in the event of seismic activity/reduce punching force from...
