In structural design, structural experts pass many kinds of subjective and fuzzy judgements which are not described obviously in formal calculation notes. The purpose of this paper is to formulate quantitatively such subjective structural judgements by means of the "Analytic Hierarchy Process (AHP)" and the "Fuzzy Confluence Rule". The former was proposed by Saaty, and the latter by the authors. In this paper, the "AHP" is applied to the formulation of damage assessments of R/C columns with flexural yielding type and R/C shear walls with shear failure type. Polynomial of degree 2 or 3 have a good approximation to the damage assessment functions of deformation. The "Fuzzy Confluence Rule" is applied to the formulation of the total damage assessment of R/C buildings composed of damaged columns and damaged shear walls and to the formulation of aseismic capacity assessments of R/C buildings in consideration of the relation of seismic damage and the time elapsed after completion. The approximate functions are expressed by the linear summation of intersection, union, algebraic summation and product functions with mutual inference parameter α, overestimation parameter β and weighting parameter γ. The all approximations of formulas are carried out by using the answers to the questionnaires distributed to practical experts of structural design. The approximated formulas show the mechanism of fuzzy and subjective judgements by structural experts and very useful for composing expert systems which enable us to assess safety and damage of structures and to perform optimum design of structures.
