An eccentric mass vibrator used at Chicago’s Soldier Field football stadium to evaluate requirements for tuned mass dampers.

Field Vibration Testing



Contact ANCO to test civil structures in the field. Since 1965 at University of California, Los Angeles (UCLA) and since 1971 at ANCO we performed over 300 field vibration tests world wide to determine the in-situ dynamic properties of structures including:




Such testing clarifies many issues:




Testing is performed with eccentric mass vibrators, impulsive exciters, and ambient vibration testing listed in ANCO products menu.
