Static indeterminacy formula
WebApr 11, 2024 · If the number of unknown reaction are more than the number of equilibrium equation available then structure is called indeterminate structure and degree of indeterminacy is given by static indeterminacy. Some important cases are: Pin jointed plane frame, Ds = m + r - 2j Pin joined space frame, Ds = m + r - 3j WebApr 16, 2016 · Another equation that can be used for calculation of degree of indeterminacy in frames is; RD = R – e – S ———— (1.4) Where; R = Number of support reactions e = Number of equations of equilibrium (i.e 3) S = Number of special conditions (e.g. internal hinge) Whenever; RD = 0 (structure is statically determinate and stable
