Predicting Concrete Structure Remaining Life Time

How to predict the structure life time? Really my Ph.D about concrete structure reliability and its probability of failure with considering the corrosion effect. I did also many researches about concrete structure, steel and offshore structures failures and its reliability but this questions raised to me from 10 years in one on my courses in Dubai. From that date I spent many times and collect many researches about how to know the structure remaining life time really it is very complicated questions and different from structure to another.
Based on that I published many books about corrosion, structure evaluation, quality control and then my book about assessment evaluation and repair concrete, steel and offshore structures, I try to address this point. The experimental technique and pushover analysis is discussed also. It is very important to highlight that in mature structure if you try to design it or evaluate it will be unsafe. I wish to delete this statement from your mind during evaluation mature structure "UNSAFE" , but say it is violating to the existing code but how long it can live until failure that we discuss about it here in this book.
For this eBook I focus about answering this question and provide many references can be used also in case for future reading. If you have any inquiry or questions or special case need to discuss let do not hesitate to contact me.
