Wood Method
The Wood method, also known as the Merchant–Rankine–Wood method, is a structural analysis method which was developed to determine estimates for the effective buckling length of a compressed member included in a building frames, both in sway and a non-sway buckling modes. It is named after R. H. Wood. According to this method, the ratio between the critical buckling length and the real length of a column is determined based on two redistribution coefficients, \eta_1 and \eta_2, which are mapped to a ratio between the effective buckling length of a compressed member and its real length. The redistribution coefficients are obtained through the following expressions: :\eta_i = \frac,\quad i = 1,2 where K_i are the stiffness coefficients for the adjacent length of columns. Although this method was included in ENV 1993-1-1:1992, it is absent from EN 1993-1-1.

Structural Analysis
Structural analysis is a branch of Solid Mechanics which uses simplified models for solids like bars, beams and shells for engineering decision making. Its main objective is to determine the effect of loads on the physical structures and their components. In contrast to theory of elasticity, the models used in structure analysis are often differential equations in one spatial variable. Structures subject to this type of analysis include all that must withstand loads, such as buildings, bridges, aircraft and ships. Structural analysis uses ideas from applied mechanics, materials science and applied mathematics to compute a structure's deformations, internal forces, stresses, support reactions, velocity, accelerations, and stability. The results of the analysis are used to verify a structure's fitness for use, often precluding physical tests. Structural analysis is thus a key part of the engineering design of structures.

Buckling
In structural engineering, buckling is the sudden change in shape (deformation) of a structural component under load, such as the bowing of a column under compression or the wrinkling of a plate under shear. If a structure is subjected to a gradually increasing load, when the load reaches a critical level, a member may suddenly change shape and the structure and component is said to have ''buckled''. Euler's critical load and Johnson's parabolic formula are used to determine the buckling stress in slender columns. Buckling may occur even though the stresses that develop in the structure are well below those needed to cause failure in the material of which the structure is composed. Further loading may cause significant and somewhat unpredictable deformations, possibly leading to complete loss of the member's load-carrying capacity. However, if the deformations that occur after buckling do not cause the complete collapse of that member, the member will continue to support the ...

EN 1993-1-1
In the Eurocode series of European standards (EN) related to construction, ''Eurocode 3: Design of steel structures'' (abbreviated EN 1993 or, informally, EC 3) describes how to design of steel structures, using the limit state design philosophy. It was approved by the European Committee for Standardization (CEN) on 16 April 2004. Eurocode 3 comprises 20 documents dealing with the different aspects of steel structure design: * EN 1993-1-1: General rules and rules for buildings. * EN 1993-1-2: General rules - Structural fire design. * EN 1993-1-3: General rules - Supplementary rules for cold-formed members and sheeting. * EN 1993-1-4: General rules - Supplementary rules for stainless steels. * EN 1993-1-5: General rules - Plated structural elements. * EN 1993-1-6: General rules - Strength and stability of shell structures. * EN 1993-1-7: General rules - Strength and stability of planar plated structures subject to out of plane loading. * EN 1993-1-8: Design of joints. * EN 1993-1- ...
