What are the various methods used to analyze indeterminate structures?

Methods Used to Analyze Indeterminate Structures

1. Finite Element Method (FEM): 

A numerical approach that divides the structure into small, manageable elements and solves for displacements, stresses, and strains using matrix equations.

2. Flexibility Matrix Method: 

Also known as the force method, it involves determining the structure's response by analyzing forces and displacements using flexibility coefficients.

3. Stiffness Matrix Method: 

Also called the displacement method, this technique calculates displacements first, using stiffness coefficients, and then determines internal forces based on the deformations.
