다국어 초록 (Multilingual Abstract)

As part of two comprehensive fatigue evaluations of replacement orthotropic bridge decks in New York City, NY, USA, in-place in 1999 and was posibly the largest field instrumentation study conducted on an in-service orthotropic deck in the USAuntil that time. The second field study was initiated in 202 on a diferent orthotropic deck and utilized more advanced remotedata acquisition and monitoring techniques. During both studies controlled load testing and uncontrolled remote monitoringwere completed. The remote monitoring systems utilized an innovative application of traditional data acquisition coupled withacquisition systems were controlled remotely using secure conections from the ATLS Engineering Research Center at LehighUniversity. This paper reports on the techniques used in the field and provides guidance on instrumentation and field monitoringof these unique structural systems.
