ABSTRACT
The main purpose of structural analysis is to determine forces and deformations of the structure due to
applied loads. Structural design involves form finding, determination of loadings, and proportioning of
structural members and components in such a way that the assembled structure is capable of supporting
the loads within the design limit states. The analytical model is an idealization of the actual structure.
The structural model should relate the actual behavior to material properties, structural details, and
loading and boundary conditions as accurately as is practicable.
