Buckling analysis and dynamic analysis of steel fiber column with different cross-section and boundary conditions using euler-bernoulli beam theory

Buckling and dynamic analysis of the Euler beam model is of great importance in mechanical, civil aviation engineering disciplines and mechanical engineering applications. With the developing technology today, engineering problems that are difficult to solve have become easily solved in a short time through computer software. The mathematical and numerical solution methods created provide significant convenience for engineering. This study includes buckling and vibration analysis of a steel fiber column formed by a known model. In the column and beam model created, characteristic values obtained from four different self-compacting concrete (KYB) series; 0.6% by volume, three different types of fiber-reinforced samples and one fiber-free (K) control sample were used. In the study, analyzes giving critical buckling values, natural frequency and frequency parameter values for the beam model depending on the diameter, length, elasticity module and cross-section type of column model were made. With the analysis results obtained, the effect of slenderness and steel fiber-containing PUE on the critical load in the pressure columns was investigated. As a result, it has been observed that fiber use provides an increase of approximately 15-20% in natural frequency and frequency parameter values and decreases the critical buckling load values.
