“…They developed a cumulative damage model resembling Miner's rule to predict the fatigue life under variable amplitude cyclic loading. The Co n-Manson rule was also employed by McCabe and Hall [5] after modifying the original fatigue-life expression by introducing the plastic ductility concept. Chai and Romstad [6] used the same formulation in terms of normalized hysteretic energy and normalized response displacement in order to evaluate the fatigue-based response of steel cantilever specimens.…”

SUMMARYEnergy dissipation characteristics of structural members which exhibit both strength and sti ness deterioration under imposed displacement reversals are investigated. In the experimental part, 17 reinforced concrete beam specimens were tested under constant and variable amplitude inelastic displacement cycles. The constant-amplitude tests were employed to determine the low-cycle fatigue behaviour of specimens where the imposed displacement amplitude was the major variable. A two-parameter fatigue model was developed in order to express the variation of dissipated energy with the number of displacement cycles. This model was then used to predict the energy dissipation of test specimens subjected to variable-amplitude displacement cycles simulating severe seismic excitations. It has been demonstrated that the remaining energy dissipation capacity in a forthcoming displacement cycle is dependent on the energy dissipated along the completed displacement path. Moreover, it is observed that total energy dissipation is dependent on the length of the displacement path.

“…e energy dissipation of different monitoring nodes, namely, the area of the load-displacement hysteresis loop, could be calculated by the numerical integration [27][28][29], and the changes of mechanical properties and development of cumulative damage were investigated through energy dissipation analysis shown in Figure 5. Figure 5 provides the energy dissipation analysis of the corresponding monitoring points of the specimens.…”

To overcome the fatigue safety problem of transmission tower cross arms caused by the wind-induced vibrations, an experimental study on the high-cycle fatigue performance of a new type of GFRP-steel sleeve composite cross arms was carried out. A total of six specimens were subjected to 500 thousand cyclic loadings based on the practical engineering background. e stress state was monitored, and a variety of load-displacement-time curves, the energy dissipation capacity, and the dynamic strain were analyzed to examine the effects of fatigue loading. After the fatigue test, the specimens without significant fatigue failure were evaluated to derive the residual bearing capacity. Based on the residual strength theory, the cumulative damage was examined, and the fatigue life was predicted under various loading conditions to ensure the reliability of composite cross arms. It is shown that the new type full-scale GFRP-steel sleeve composite cross arms can demonstrate a high level of safety redundancy on antifatigue performance and can be expected for wide application in power transmission towers.

“…Cumulative indices, on the other hand, contain a specific component that makes it possible to consider the cumulative aspects of damage .This component can be based on deformation [13], hysteretic energy [14], or low-cycle fatigue formulations [15]. Some combinatory indices are also proposed.…”
