Computational analysis methods

Below is a brief summary of computational analysis methods that covered in this section.

Static analyses

Static analyses can be classified as (Ziemian 2007):

• 1st order elastic analysis: $[K_{e}]{\Delta }=\{F\}$
• 2nd order elastic analysis: $[K_{e}+K_{g}]{d\Delta }=\{dF\}$ (P-Delta effects are considered)
• 3rd order elastic analysis: $[K_{e}+K_{g}]{d\Delta }=\{dF\}$ (large displacements are considered)
• 1st order inelastic analysis: $[K_{e}+K_{p}]{d\Delta }=\{dF\}$
• 2nd order inelastic analysis: $[K_{e}+K_{g}+K_{p}]{d\Delta }=\{dF\}$ (P-Delta effects are considered)
• 3rd order inelastic analysis: $[K_{e}+K_{g}+K_{p}]{d\Delta }=\{dF\}$ (large displacements are considered)
