ERROR INTERPOLATION FOR REFERENCE VALUE CHARACTERIZATION FOR COMPLEX COLUMN BUCKLING PROBLEMS

Resumo

For convergence verification of the column buckling problem it is necessary to obtain a good
reference value to compare the values obtained during the numerical process, in most cases the reference value
used is given by an experimental data or the result obtained by an analytical solution. In this way, the purpose of
the present study is to analyze a critical load buckling problem in a continuous beam that have analytical solution
and compared with curve fitting reference value obtained by Finite Element Method. The methodology applied
seen to be reliable and applicable to problems that does not have analytical solution.
