9. Non-Linear Combinations Overview 35 Scaffolding Global analysis aims at determining the distribution of the internal forces and moments and the corresponding displacements in a structure subjected to a specified loading. The first important distinction that can be made between the methods of analysis is the one that separates elastic and plastic methods. Plastic analysis is subjected to some restrictions. Another important distinction is between the methods, which make allowance for, and those, which neglect the effects of the actual, displaced configuration of the structure. They are referred to respectively as second-order theory and first-order theory based methods. The second-order theory can be adopted in all cases, while first-order theory may be used only when the displacement effects on the structural behavior are negligible. The second-order effects are made up of a local or member second-order effects, referred to as the Pδ effect, and a global second-order effect, referred to as the P-Δ effect. On the next page an overview of the global analysis following the EN 1993-1-1, chapter 5, will be given: o All the rules in this overview are given in the EN 1993-1-1 art. 5. For each step the rule will be indicated. The first rule (αcr > 10) will be explained in EN 1993-1-1 art. 5.2.1(3). o In this overview 3 paths are defined: Path 1: In this path a first order calculation will be executed Path 2: In this path a second order calculation will be executed with global (and bow) imperfections. Path 3: In this path a second order calculation will be executed with the buckling shape of the construction as imperfection. o The calculation will become more precise when choosing for a higher path. o The lower paths will result in a faster calculation, because a first order calculation can be executed without iterations, but this first-order theory may be used only when the displacement effects on the structural behavior are negligible. o In the next paragraphs the rules in this overview will be explained. To take into account all non-linearities in the model, non-linear load combinations are made.
