Accelerometer correction for the dynamic analysis of damped multi-degree of freedom systems

G. A. MCLENNAN

DEPARTMENT OF MECHANICAL AND AERO-SPACE ENGINEERING UNIVERSITY OF MASSACHUSETTS, AMHURST, MASSACHUSETTS

Abstract

An exact method is developed to eliminate the accelerometer error in dynamic response calculations for damped multi-degree of freedom systems. It is shown that the exact responses of a system can be obtained from the approximate responses which are conventionally calculated from an accelerogram.

Response calculations were performed for two typical systems with three degrees of freedom for an assumed pseudo-earthquake. The results showed that the approximate responses may contain large errors, and that the correction developed effectively eliminates these errors.
