Modal testing is a developing expertise in the field of structural dynamics. However, in practice the models that are produced by modal testing procedure face different errors. One of the sources of error is mass-loading effects of accelerometers. This article targets the elimination of mass-loading effects of accelerometers from measured frequency response functions. A strategy based on sensitivity analysis is introduced for this purpose. In this approach the amount of added masses and the locations of structural responses are selected based on the minimum error in correction method. A mass-spring-damper system is used to validate the method numerical. Also, a steel beam is examined to demonstrate the applicability of method in practical cases. The numerical and experimental case studies show the effectiveness of the proposed method.
