Usually, these fluid dampers are rate-independent and used in conjunction with elastomeric isolators to insulate the base of buildings (buildings, bridges, etc.) to reduce the shocks caused by earthquakes by increasing the damping capability. According to the EN 15129 standard, the velocity-dependent anti-seismic devices are Fluid Viscous Dampers (FVDs) and Fluid Spring Dampers (FSDs). Based on experimental data from a dynamic regime of a fluid viscous damper of small dimensions, for which not all the design details are known, to determine the law of behavior for the viscous damper, the characteristics of the damper are identified, including the nonlinear parameter \u03b1 (exponent of velocity V) of the constitutive law. Note that the magnitude of the fluid damper force depends on both velocity (where the maximum value is 0.52 m\/s) and amplitude displacement (\u00b125 mm). Using the Kelvin\u2013Voigt rheological models, the dynamic response of a structure fixed with a fluid viscous device is analyzed, presenting the reaction force and displacement during the parameterized application of an external shock. This new approach for FVDs\/FSDs was validated using the standard deviation between the experimental data and the numerical results of the extended Kelvin\u2013Voigt model offering researchers in the field of seismic devices a reliable method to obtain a constitutive law for such devices.<\/jats:p>","DOI":"10.3390\/computation11010003","type":"journal-article","created":{"date-parts":[[2022,12,27]],"date-time":"2022-12-27T04:35:43Z","timestamp":1672115743000},"page":"3","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A New Modeling Approach for Viscous Dampers Using an Extended Kelvin\u2013Voigt Rheological Model Based on the Identification of the Constitutive Law\u2019s Parameters"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2306-2784","authenticated-orcid":false,"given":"Ovidiu","family":"Vasile","sequence":"first","affiliation":[{"name":"Department of Mechanics, University POLITEHNICA of Bucharest, 060042 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2927-1405","authenticated-orcid":false,"given":"Mihai","family":"Bugaru","sequence":"additional","affiliation":[{"name":"Department of Mechanics, University POLITEHNICA of Bucharest, 060042 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,27]]},"reference":[{"key":"ref_1","unstructured":"(2022, November 20).
