A summary of time-varying reliability analysis of existing structure based upon Bayes method;

Time-dependent reliability of existing structure in acid gases;

Probability model and statistical parameters of resistance for existing structure;

For ultrasonic-resilient technology of integrated law testing concrete strength,the paper discusses ultrasonic-resilient comprehensive law measuring strong principles,factors and test methods for concrete testing service structure used for drilling core France calibration,and presents a core kind of test accuracy and a theoretical analysis.

On the basis of carbonization testing of concrete in service structure and related civil and foreign datum,major factor(influencing) concrete carbonization is analyzed and mathematical model of concrete carbonization in service structure is founded and method restraining concrete carbonization is put forward.

This paper describes the necessity of safety inspection of offshore structure in service period taking practice as base, introduces the inspection concept and technology, analyzes preliminarily sensitivity factors which affect the structural safety > and approaches reasonable design problem of the inspection point.
