Effect of Temperature

Percent of the room-temperature value against temperature, digitized from the handbook figures (the shortest exposure of each figure, every 10 °F). Strength curves give the allowable at temperature; "after exposure" curves give the room-temperature property after a soak at that temperature.

Moduli at temperature

Stress-Strain Curves (Ramberg-Osgood)

ε = σ/E + 0.002 (σ/F_y)^n with the first band's A-basis yield strength and the exponent on file for it (the tension curve stops at F_tu).

Ramberg-Osgood design stress-strain curves at room temperature
