  critical buckling load
The average critical buckling load of 186.56 kN was obtained by using the Patran finite element analysis (FEA).
      
The critical buckling load resulting from a stability analysis has been evaluated, based on Dirichlet-Lagrange criterion.
      
The result shows when impact load acts on the shells, a jump of the shell takes place dependent on the values λ and the critical buckling load increases with the enlargement of the loading area.
      
A condition of stability is derived, and the critical buckling load is obtained.
      
Therefore, from these relationships one can easily obtain the exact RPT and FPT solutions of critical buckling load and natural frequency for a circular plate with CPT solutions.

26 steal bracket plates of different geometric shapes are tested and analysed by FEM. The result shows that the strength formula of bracket plate deduced by the "cantiliver-beam-method" is incorrect when a/b≤0.75.The formula for calculating the strength and buckling load are presented in this paper.

Shuttle shape lattice column (SLC) formed by steel pipes and horizontal diaphragms as a latticed column with varying section is being used and extended to many public buildings recently. In this paper, elastic buckling behavior of SLC subjected to axial compressive forces has been investigated theoretically by employing a powerful finite element analysis package ANSYS. Three kinds of latticed columns constrained by pin connections at two ends are involved in the analysis. They are single steel pipe column, two steel pipe latticed column and three steel pipe latticed column where the two or three pipes are combined as a whole by welding horizontal diaphragms to the pipes. Parameter studies for the elastic bifurcation buckling and corresponding buckling mode of the latticed columns have been carried out. The obtained results indicates that the SLC generally behaves as two different buckling modes which are dependant on their slenderness ratio, length, numbers and thickness of horizontal diaphragms, and so on. This conclusion is very helpful to design such SLC employed in Guangzhou New Baiyun International Airport.
