Most structures are composed of many members of elements. The reliability of a structural system will be a function of the reliability of its members. Any real structural system usually requires a combination of both series and parallel descriptions for its subsystems. The paper presents the building of a knowledge base of an expert system for defining reliability state of construction. The linguistic values of elements state are obtained by experiments and experts opinions. Structures are defined by reliability network considered as a system composed of elements. We associate will each component in a complex structure a linguistic state variables. The final computational step is to determine a single linguistic estimate of the state of the construction. The difficult problem of reliability assessment of structures is subdivided into smaller problems for each element. Then, the analysis for the whole structures we may investigated, when we have estimated a damage level for the elements.
