Fatigue Limits for Prestressed Reinforced Concrete Beams
Fatigue Limits for Prestressed Reinforced Concrete Beams
(OP)
I am currently trying to analyze fatigue limits for a reinforced (PPF) concrete beam that has both non-prestressed and prestressed r/f. The beam is fairly large [450mmx800mm] , with compression and tension standard r/f and pretensioned r/f.
Does anyone have a good reference source (dated preferably after 2000) on how to calculate/estimate the fatigue limit or number of cycles before failure for this type of reinforced concrete beam (or similar)? I have read some references stating that the reinforcing steel will be the governing factor, but I have had no luck in finding an estimating method to determine this. All I found on this topic is a report from Aug 1984 from the Uniersity of Michigan thatgoes over some data results, but as this is somewhat dated I was hoping to find a more recent article.
Thanks in advance! Looking forward to the discussion. If I am missing any information that is needed to find the correct source, I will try and answer the best I can.
