WebNov 4, 2024 · The Degree of Static Indeterminacy (DOSI) is the difference of the number of unknown forces and the number of equilibrium equations. Therefore: DOSI = 0; structure is statically determinate. DOSI > 0; structure is statically indeterminate. DOSI < 0; structure is unstable. For frames (and beams ): For trusses: r = number of reaction components
