Abstract. This work presents results of integrated experimental and numerical study of destruction of reinforced concrete beam made of concrete and fiber concrete under shortterm dynamic loading. Experimental studies were carried out using pile driver. Short-term dynamic loading acting on a beam was applied by falling weight, 450 kg, from the height 700 mm. The value of dynamic load in experiments was defined by means of force gauge, linear displacement transducers were used to define linear displacements. Numerical simulation was held three-dimensionally within phenomenological approach of continuum mechanics, the reinforcing elements were clearly defined. Finite element method was modified to solve dynamic tasks. Impact of load on a beam in calculations was replaced by impulse. The dependence of impulse on time was defined from the experiment. The influence of reinforcement on deformation and beam destruction was studied. Correlation of experimental and numerical data was performed.

Abstract.Results of the study on the operation of the reinforced concrete columns joints without reinforcement and reinforced by metal casing under short-term dynamic loading are presented in the paper. Program of experimental and numerical studies was developed. As a result of experimental studies schemes of deformation, cracking and fracture, as well as values of fracture loads of experimental samples were obtained. Present results are compared with data of the numerical calculations performed using the computational program based on finite elements method. Results of experimental and numerical calculations showed good convergence and reliability of columns joints strengthening by metal casing.

“…Earlier conducted researches of the fracture of the spaced barriers made from isotropic metal materials have shown that their efficiency, in comparison with efficiency of the monolithic barrier, increases with increase in velocity of interaction. Now for manufacturing of aircrafts elements the various types of composite materials having a high degree of anisotropy of the elastic and strength properties are used, and without such property as anisotropy it is impossible to describe and predict the behavior of design elements and of the design as a whole (Radchenko & Radchenko, 2011). …”
