Estudo numérico-experimental do dano produzido por fadiga em jaquetas de plataformas marítimas

This work presents a method for obtaining the acumulated fatigue damage in the welded joints of a jacket type platform, based on measurements carried on the platform during its operation. The technique of random data measurement and analysis is presented, emphazising the aspects of measuring on the sea. After this the mathematical modeling of the structure, by means of a computer, is discussed. Transfer functions are obtained between deck displacements and member stresses, with the help of a structural analysis program. Having them been determined, the fatigue damages are calculated for selected joints. The results achieved by the proposed method are compareci with those obtained by in situ measurements and with the conclusions of the structure original project.
