Linear Static analysis is the default analysis method that SkyCiv’s Structural 3D uses to analyze structures. Compared with non-linear analysis, linear analysis is an efficient method of solving a structure as it assumes the structure to behave in an elastic manner.
Linear static analysis has two main assumptions:
Often, linear analysis is sufficient for the solution of most structures with the structures themselves assumed to have small deformations. Note that modern design codes are written in such a way that there is a large factor of safety already accounted for in the design of a structural element. This makes it ideal for a majority of the strucutres structure. As the assumptions are elastic, this makes it most ideal with structures that are made of Hookean materials such as steel.
