Abstract
This paper is concerned with both statically and kinematically indeterminate bar-and-joint assemblies. It investigates whether the kinematic indeterminacy appears in the form of a first-order or a higher-order infinitesimal mechanism. It is shown that the method by Calladine and Pellegrino and the method by Kuznetsov can be synthesized in a unified approach based on the Hellinger-Reissner principle. In the case of a single state of self-stress, examples are presented.
