Abstract: The project focuses on the dynamic analysis of concrete beams reinforced with silica-nanoparticles under blast loading. The structure is located at two boundary conditions. The effective composite properties are obtained utilising Mori-Tanak theory. The structure is simulated with sinusoidal shear deformation theory. Applying strains and stress, the beam energies are derived and utilising principal of Hamilton, the final equations are calculated. Using method of differential quadrature (DQM) and Newmark, the structure dynamic deflection is obtained. The influences of volume fraction and agglomeration of silica nanoparticles, parameters of geometrical, boundary condition and blast load on the dynamic deflection are studied. Based on results with enhancing volume fraction of silica nanoparticles, the dynamic deflection decreases.

Keywords: dynamic analysis; concrete beam; DQM; silica nanoparticle.
