    Abstract. The article provides information about the parameters of the loads from the action of an explosion when interacting with a free-standing building. The calculation of a one-story industrial building according to the first limit state, which is characterized by the operation of structures in the conditionally elastic stage of deformation, was carried out using two methods. An algorithm is presented for calculating reinforced concrete structures for the effect of an explosive load, taking into account diffraction by the quasi-static method, as well as by the dynamic method using the LIRA 10 calculation complex - the method of direct integration of the equations of motion. A comparative analysis of the frequencies of natural vibrations of structures, displacements and forces obtained by quasi-static and dynamic methods of calculation for explosive loads was carried out. Conclusions are drawn about the advantages and prospects of the dynamic method of calculating industrial buildings under explosive loads using domestic calculation complexes.
    Keywords: industrial building, reinforced concrete structures, explosive loads, methods of direct integration of equations of motion, dynamic calculation method, quasi-static calculation method, dynamic coefficient
