| Abstract: | Research of random temperature and ramdon creep stress in mass concrete structures is becoming more and more important for practical engineering. This paper discusses random environmental factors, random physical parameters, random hydration heat of concrete as well as the properties of concrete aging and creep etc., and reviews systematically various methods for the analysis of random temperature and random creep stress of concrete structures. The suitability of those methods and the key problems needed to be solved in the future are pointed out. Some pertinent comments are also made. |
