It uses elastic buckling results to determine the ultimate strength through the use of empirical strength curves.
2.
An increase in prediction confidence stems from forced compatibility between section flanges and web throughout elastic buckling analysis.
3.
The finite strip method using CUFSM is the most commonly used approach to determine the elastic buckling loads.
4.
Nonlinear elastic behavior derives from a multi-axial elastic instability of the lattice, a complex coordinated elastic buckling of the strut members.
5.
Elastic buckling of a " heavy " column i . e ., column buckling under its own weight, was first investigated by Greenhill at 1881.
6.
In general these would include : ( 1 ) determining the elastic buckling values and ( 2 ) using the DSM equations in Appendix 1 to determine nominal flexural and axial capacities, Mn and Pn.
