temperature load in outdoor steel structure
temperature load in outdoor steel structure
(OP)
For outdoor industrial structures, the forces to be caused by ambient temperature change is something we’re lack strong guidance and big confidence. Some always considered this load case, some never did by saying: the deformation (slid) at bolted connections will accommodate the temperature expansion/contraction. What do you think?

The design of sliding bearings is interesting, I have seen some designers have steel sliding on steel with large slots, and others with slide bearings that have teflon plates and mirror finished stainless steel in contact. Con-Slide is one system I have used. I have also used Masticord elastomeric pads.

Someone argues that the structures designed without this load case have been in operation for many years. I think this is because they followed some besign rules like expansion joint every 100ft, for piperack for example, and single anchor bay. In this case member exapansion/contraction doesn't cause big force. On the other hand, when I consider member temperature I usually model the piles with springs, this sometimes will make a big difference.
