displacement method structural analysis examples

While displacement method of analysis of indeterminate structure is suitable when degree of freedom is less, i.e, degree of kinematic Indeterminacy is less than degree of static Indeterminacy.

Force method of analysis of indeterminate structure is suitable when degree of redundancy is less, i.e, degree of static Indeterminacy is less than degree of kinematic Indeterminacy.

While in case of displacement method of analysis of indeterminate structure, first force displacement equations are written and then unknown displacement are calculated from equilibrium equations at joints. forces in a roof or bridge truss, than did the displacement method.

In force method of analysis of indeterminate structure, first force displacement equations are written and then unknown forces are calculated from compatibility criteria. (4) Examples indicate that certain problems can be solved.While in case of displacement method of analysis of indeterminate structure, the unknowns are taken as displacement (i.e, Δ or ө). In force method of analysis of indeterminate structure, the unknowns are taken as forces (i.e, member forces or reaction).To analyze an indeterminate structure, some additional equilibrium or compatibility equations are required.

For an indeterminate structure, the condition of static equilibrium equations are not sufficient to analyze the structure. The crystalline structures and lattice parameters of Ba 1x Bi 2x/3 (Fe 0.5 Nb 0.5) 0.025 Ti 0.975 O 3 ceramics whose rate x varies between 0 and 0.15 were studied at room temperature by means of the XRD data, which was refined using Fullprof suite software 14, 15.
