Difference between Determinate and Indeterminate Structure

June 18, 2019

Determinate structure	Indeterminate structure
1. When all forces in a structure is determined from equilibrium equations, the structure is known as statically determinate.	When the unknown forces in a structure are more than the available equilibrium equations, that structure is known as statically indeterminate structure.
2. Support will not develop moment and horizontal force to prevent collapse.	Support will develop moment and horizontal force to prevent collapse.
3. No load redistribution.	Tendency to redistribute load.
4. Bending moment and shear force at any section of beam is independent of material property and cross section of the structure	Bending moment and shear force at any section of beam is depends on material property and cross section of the structure.
5. No stresses due to lack of fit and temperature variations.	Stresses caused due to lack of fit and temperature variations.
