Abstract

Nowadays, with the
help of developing technology, engineering problems which are difficult to
solve have become easily solved in a short time by means of computer software. Certain mathematical algorithms
are used in these analysis methods. The mathematical and numerical solution
methods created provide a significant solution facility for engineering. In
this paper, the buckling analysis of the Euler column model, with elastic
boundaries and containing steel fibers, under pressure effect is performed. In
the column model, three different sections, which have been produced from four
different concrete series, including three different types of fiber reinforced
specimens and one non-fibrous control sample(C) with 0.6% by volume, were
analyzed by using a software. In the study, the
analysis of the critical buckling values depend on length, elastic modulus and
cross-sectional type of the column model has been performed. The results are
shown in graphs and tables. With the results of the analysis, the effect of
slenderness and steel fiber concrete on the critical load in pressure columns have
been investigated.
