ABSTRACT:
The invention concerns a method of dimensioning and producing stiffened structural components (4) comprising at least one shell component (6) and at least one stiffening component (8) which can be connected thereto, in which the shell component (6) and the at least one stiffening component (8) is dimensioned on the assumption of intactness of the at least one stiffening component and having regard to a predetermined safety factor and/or a predetermined structural inspection interval in which a predetermined maximum crack progression in the shell component is not to be exceeded and/or the strength of the structural component is not to fall below a predetermined minimum residual strength, and in which the at least one stiffening element (8) of the structural component dimensioned by this method is equipped with at least one structural condition sensor (30) for detecting intactness; as well as the use of structural condition sensors in an aircraft, in particular a passenger aircraft.
