Structural Analysis
Assume a temperature change of 70 °F after erection when calculating thermal movement in one direction (not total). Take T
min
= 10 °F and Tmax
= 80 °F. For the panhandle region use Tmin
= 10 °F and Tmax
= 115 °F, for a total temperature change of 105 °F. Optionally, the temperature ranges in Article 3.12.2.2 may be used if appropriate.Do not include shrinkage, creep, and elastic shortening when determining maximum movement, which will be accommodated through infrequent slip.
Use the critical DL condition (the lightest predicted DL) when checking against slip.
Use Load Combination Service I for all gravity loads.
Use load factor for uniform temperature (TU) of 1.0.
Ignore limit on
