Buckling Load Analysis of Variable Section Column and Steel Lattice Column

The parameter transformation method is used to study the buckling load of variable section column and steel lattice column, and obtain the buckling modes of variable section column and steel lattice column. According to the boundary conditions, the characteristic equation to determine the buckling load is derived, and the buckling load can be obtained by solving the characteristic equation. Compared with the Bessel function method, parameter transformation method is more simple and has high accuracy.
