У меня предварительный стандарт в области строительства. По всему тексту проходит словосочетание rational analysis. Перевожу его как рациональный анализ. И вдруг закралась мыслишка - а прав ли я вообще-то?

Вот примеры предложений:
The location of maximum structural action in a nonprismatic member shall be determined by rational analysis for the member geometry and loading under consideration.

(a) Braced Frames. In braced-frame structural systems, where lateral stability is provided solely by diagonal bracing, shear walls or equivalent means, the effective length factor, K, for compression members shall be set equal to unity (1.0) unless a rational analysis shows that the end restraint conditions justify the use of a smaller value.

(b) Unbraced Frames. In frames where lateral stability depends on the flexural stiffness of beams, columns and their connections, the effective length factor, K, of compression members shall be determined by rational analysis.

For unequal leg single angle sections subjected to compression, the factored flexural-torsional buckling
strength shall be computed by rational analysis.

Развейте, пожалуйста мои сомнения, или подскажите :)

Заранее Спасибо.
