How To Calculate Static Kinematic Indeterminacy Explained Part 1 For beams and framed structures, the formula below can be used to check the degree of static indeterminacy of the structure. d = s i 3m – 3p. where; d = degree of static indeterminacy. s = number of support reactions. i = number of internal forces in hinges (usually 2 per internal hinge) m = number of closed loops without hinges. After that, the value of external static indeterminacy has calculated (dse). now to calculate the total degree of static indeterminacy internal and external static indeterminacy has added. at last value of kinematic indeterminacy has calculated. one support is hinge has one, and there is one hinge which has three kinematic indeterminacy.
Static Indeterminacy 2 Youtube Figure 1.11. crossbeam layer 1.4. kinematic static indeterminacy when a structure is stressed by one or more external actions, the joints of this structure undergo deflections. the method of displacements advocates rotations and displacements of the joints of the structure as unknowns of the problem. Formulations for stability and determinacy of beams and frames. the conditions of determinacy, indeterminacy, and instability of beams and frames can be stated as follows: \[\begin{array}{l} 3 m r<3 j c \text { structure is statically unstable} \\ 3 m r=3 j c \text { structure is statically determinate}\\ 3 m r>3 j c \text { structure is statically indeterminate} \end{array}\]. In this video you will learn about the static indeterminacy and kinematic indeterminacy which important aspect for structural analysis. through this video yo. The degree of static indeterminacy is equal to the number of redundant equations of equilibrium and depends on the number of members (m), joints (j), and external reaction components (r). examples are given to demonstrate calculating the degree of redundancy for different plane frame and grid structures. 1.1 static and kinematic indeterminacy.

The calculation of static indeterminacy, denoted as ‘d s ‘, is essential for understanding how to analyze and design a structure effectively. it is determined by the formula: ds = r – e. where ‘r’ represents the number of unknown reactions and ‘e’ represents the number of equilibrium equations available. in three dimensional. Determinacy, indeterminacy, and stability of structures: a structure is determinate if the number of unknown reactions is equal to the number of static equilibrium. thus, the equations of static equilibrium are enough for the determination of the supports for such a structure.
