a) Corrosion fatigue,
b) Low cycle (high stress) fatigue,
c) Thermal fatigue,
d) Stress corrosion cracking,
e) Effects of high temperature ( ), and
f) Effects of low temperature (< brittle transition temperature).
19.1.1 For the purpose of design against fatigue, different details (of members and connections) are classified under different fatigue class. The design stress range corresponding to various number of cycles, are given for each fatigue class. The requirements of this Section shall be satisfied with, at each critical location of the structure subjected to cyclic loading, considering relevant number of cycles and magnitudes of stress range expected to be experienced during the life of the structure.
