CUMULATIVE DAMAGE IN STEEL STRUCTURES SUBJECTED TO EARTHQUAKE GROUND MOTIONS
Experimental data are presented from low cycle fatigue tests of structural steel components. In these tests the failure of local buckling in beam flanges and fracture at weldments were studied in detail. Cumulative damage models are proposed which permit a life prediction for arbitrary cyclic loading histories. For the local buckling failure mode a series of linear damage models is used to predict deterioration threshold and deterioration, whereas a single model is used for the fracture mode. Crack propogation at weldments is modeled with a crack growth rate model based on the plastic strain range. Adequate predictions of lives were obtained from the analytical models. (Author/TRRL)
