Under　vibration　conditions,　continuous　alternating　loads　cause　fatigue　damage　to　structures,　affecting　their　stability,　durability,　and　overall　safety.　In　this　paper,　the　additional　damping　structures　with　entangled　metallic　wire　material　(EMWM)　is　proposed.　Dynamic　tests　with　different　loading　frequencies　and　loading　amplitudes　are　carried　out　to　evaluate　the　energy　dissipation　and　stiffness　characteristics　of　the　different　structures　in　terms　of　energy　dissipation,　loss　factor,　and　average　stiffness.　Fatigue　tests　are　conducted,　and　the　fatigue　life　tests　are　applied　with　different　loading　amplitudes　and　loading　frequencies　using　displacement　control,　and　the　fatigue　properties　are　obtained　under　different　numbers　of　cyclic　loading.　The　test　results　are　analyzed　with　respect　to　the　energy　dissipation　mechanism　of　EMWM　and　the　characteristics　of　the　additional　damping　structure.　The　hysteresis　curves　under　different　loading　times　are　identified　by　parameters,　and　the　fatigue　mechanical　models　are　constructed.　Comparison　between　the　predicted　data　of　the　model　and　the　hysteresis　curve　data　of　the　test　indicates　that　the　model　has　high　accuracy.　©　2024　John　Wiley　&　Sons　Ltd.
