Abstract
Techniques are examined for the analysis of structures in which the dimensions of some or all members may be changed. Several existing methods which do not require complete reanalysis are considered, and a new procedure is proposed. The theory of each method is presented, using a consistent notation, and expressions for the number of computer operations are derived. Operation counts for a typical rigid frame are compared for the several methods. Potential advantages of iteration and substructure analysis are briefly noted. It is concluded that complete reanalysis is likely to be the most efficient procedure in the majority of cases.
