    Structure consists of different components such as slabs, beams, columns, etc. The structures have to satisfy fundamental criteria such as strength, stiffness, durability or compatibility for their existence.

    Determinate structures: If the number of unknown quantities are less than or equal to number of static conditions of equilibrium available then it is called as determinate structure.

    - To analyze determinate structures, equilibrium conditions are required. Different types of determinate structures are simply supported beams, cantilever beams, three hinged arcs, etc.

    Indeterminate structures: Indeterminate structures have number of unknown quantities more than available conditions of equilibrium. These structures are also called as redundant structures.

    - To analyze indeterminate structures along with equilibrium conditions, additional deformation conditions are also required. Different types of indeterminate structures are fixed beams, continuous beams, fixed arches, etc.
