Abstract: Structural resistance changes greatly with time in adverse environment (for example,chemical environment).The minimum resistance method is presented for reliability analysis of structures considering resistance change with time and is compared with the method given by the current building codes and the equal resistance method.The feature of the three methods is analyzed.The idea that the minimum resistance time can be taken as a key point for structural reliability analysis is presented.The minimum resistance method is simple in calculation,intuitive in concept and compatible with the current building codes.It can be a reference when analyzing reliability of structures in adverse environment.

Key words: structure, random process, time-dependent reliability, minimum resistance
