PROBABILISTIC DESIGN FOR RANDOM FATIGUE LOADS

STATIONARY RANDOM (OR STOCHASTIC) PROCESSES HAVE BEEN USED AS A STATISTICAL MODEL FOR LOADING DUE TO EARTHQUAKES, WIND, OCEAN WAVE FORCES, AND VEHICLE ENVIRONMENTS AND MOTIONS. GIVEN THAT THE DYNAMIC FORCES ON AN ELEMENT ARE A RANDOM PROCESS, THE DESIGNER IS REQUIRED TO SPECIFY THE SIZE OF THE ELEMENT SUCH THAT IT WILL MAINTAIN ITS STRUCTURAL INTEGRITY WITH SPECIFIED PROBABILITY AND AT THE SAME TIME PROVIDE A MINIMUM-COST, MINIMUM-WEIGHT COMPONENT. AN ALGORITHM FOR THE DESIGN OF A SINGLE ELEMENT (SUCH AS A TENSILE MEMBER, RIVET, BOLT, OR WELD) SUBJECTED TO A STATIONARY ZERO-MEAN RANDOM STRESS IS PRESENTED. FATIGUE WAS CONSIDERED TO BE THE MODE OF FAILURE.
