Abstract

This paper describes a technique which may be useful for selecting strain gages for use in load equations. The technique is an adaptation of the previously used T-value method and is applied in this paper to a multispar structure. The technique, called the modified T-value method, is used to reduce the number of strain gages used in a load equation from 12 to two. A parallel reduction is made using the previously developed T-value method. The two methods are compared by calculating relative equation accuracies from three applied load distributions. The equations developed from the modified T-value method proved to be accurate more consistently than the T-value method.
