Question

Degree of freedom in structural analysis

Answer 1

It is a procedure or method followed to find and measure the effect of external forces on the physical objects like built structure elements. It is used to forecast the behavior of structure upon loads acting on them. Design of element sizes, material to be used for structural elements is done on the basis of structural analysis.

Analysis is done, once visualizing the structural behavior under different types of loading. The structure should be capable to survive the loading minus any excessive deformation and internal stresses more than resisting capacity of elements.

Methods used for structural analysis depends on the type of element under study. Trusses are axial elements (resisting axial forces), which can be analyzed using method of joints, and method of sections.
