Abstract: The buckling analysis of concrete beam containing silica oxide (SiO₂) nanoparticles is investigated by Timoshenko beam model. The agglomeration effects are assumed by Mori-Tanaka approach. The beam is located in soil medium with spring and shear elements. The final equations are derived by Hamilton's principle and energy method. The equations are solved by a numerical approach and the buckling load is calculated and the influence of nanoparticles agglomeration and percent as well as geometrical parameters of the beam are investigated. The results show that the agglomeration of nanoparticles can reduce the buckling load of the beam.

Keywords: buckling of beam; agglomeration of nanoparticles; numerical approach; SiO₂.
