corrosion in tension members

[bhart192]

We have a number of bars that will be in tension load , some have corrosion we're looking for some guide to establish a standard for reject or repair baseline based on physical measurements . Thanks

What kind of bars??

What type of corrosion?

Bhart:

Generally, you look at reduction in area caused by the corrosion and compare that to some allowable stress that you are comfortable with, or one that some code dictates. Maybe you design to tolerate some of this or as a function of how critical a failure would be. You look for defects like cracking and pitting which might act as stress raisers or critical notches, particularly in highly stressed areas or changes in cross section. Also, as a function of type of loading, type of material, and the environment causing the corrosion, there are different types of corrosion which might be more detrimental, more quickly, than others. You must study and define your problem better than you have in the OP. There are plenty of structural failures caused by these types of problems from which to learn.
