In these methods flexibility and stiffness properties of members are employed. These methods have been developed in conventional and matrix forms. Here conventional methods are discussed. Thegivenindeterminatestructureisfirstmadestaticallydeterminatebyintroducing suitable numberof releases. The number of releases required is equal to Introductionofreleasesresultsin staticalindeterminacy∝s. displacementdiscontinuitiesatthesereleases under the externally applied loads.
