Evaces 2009 Drobin

Experimental vibrationanalysis is fast developing technology applied in civil engineering.Owners and users of the civil engineering structures require moresafe, reliable and comfortable structures with low life cycle costs.The experimental vibration analysis offers valuable information andsolutions for all above demands. Experimental vibrationanalysis is multidisciplinary area which can be defined ascombination of civil engineering, electronic engineering and softwareengineering. The experts in this field should be familiar with themethods of data acquisition (sensors, excitation methods, metrologyproblems, etc.), data treatment (signal processing methods) andanalysis (modal analysis, damage detection algorithms, etc.). Fastdevelopment of technologies used in experimental vibration analysisstimulates needs of international exchange of the knowledge andexperience in the field of dynamic identification and assessment ofcivil engineering structures. Forum for the contacts is created by the International Conferences Experimental Vibration Analysis forCivil Engineering Structures EVACES. The first conference EVACES’05has been held in Bordeaux, France in October 26 – 28, 2005 and thenext – EVACES’07 – has been organized in Porto, Portugal inOctober 24-26, 2007. The3rdInternational Conferences Experimental Vibration Analysis for CivilEngineering Structures EVACES’09 is held in Wroclaw, Poland duringOctober 14 16, 2009. The Conference covers the main aspects of theexperimental vibration analysis: vibrations of large structures,excitation and measurement techniques, system identification andmodel updating, vibration data analysis, mitigation of vibrations,vibration analysis of bridges, assessment of traffic inducedvibrations, structural integrity assessment and damage detection,laboratory experiments and structural monitoring. The two-pageabstracts and full contributions, including 6 invited keynote papersas well as 72 technical papers prepared by authors from 25 countries,are assembled in this book of EVACES’09 proceedings and in theincluded CD-ROM, respectively. All published papers have beenaccepted on the basis of the international review procedure. The EVACES’ 09conference is organized by Wroclaw University of Technology with theinstitutional sponsorship of the International Association for Bridgeand Structural Engineering (IABSE), International Association forBridge Maintenance and Safety (IABMAS) as well as the StructuralAssessment, Monitoring and Control Association (SAMCO). Main topics Vibration measurement (transducers, techniques, equipment) Vibration data analysis (modal analysis, wavelets, non linear non stationary processes, stochastic methods) Methodologies and standards in vibration analysis Sources of excitation (testing machines, traffic loads, ambient excitation) System identification, model updating and validation Structural integrity assessment Structural monitoring by experimental vibration analysis Vibration isolation and mitigation (passive damping, semiactive and active control) Vibration tests of buildings, bridges, roads, railways and other civil engineering structures In-situ and laboratory experiments, benchmarks Effects of shock and vibration on humans and facilities Earthquake engineering tests
