In addition, this bridge has also been used for structural health monitoring studies. 83 sensors were installed on the bridge and surrounding soil to monitor the action of the bridge after construction. This paper presents the modal identification of the bridge based on experimental data. The Eigensystem Realization Algorithm (ERA) in conjunction with the Natural Excitation Technique (NexT) is employed to analyze the ambient vibration records from sixteen of the eighty-three channels of acceleration from the bridge. To validate the modal identification results, estimated modal parameters are compared to those from the finite element model of the bridge and the identification results from other researchers. 000012313 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000012313 653__ $$aNExT, ERA, modal identification, Bill Emerson Memorial Bridge, cable-stayed bridges 000012313 7112_ $$a14th World Conference on Earthquake Engineering$$cBejing (CN)$$d2008-10-12 / 2008-10-17$$gWCEE15 000012313 720__ $$aZhang, Yuxin$$iCaicedo, Juan M.$$iSim, S.H.$$iChang, C.M.$$iSpencer Jr., Bill F.$$iGuo, Xun 000012313 8560_ $$ffischerc@itam.cas.cz 000012313 8564_ $$s537506$$uhttps://invenio.itam.cas.cz/record/12313/files/S06-017.pdf$$yOriginal version of the author's contribution as presented on CD, Paper ID: S06-017. 000012313 962__ $$r9324 000012313 980__ $$aPAPER
