Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 10, рр. 140-152. In Rus. The relevance of the work is caused by the increased probability of short-term shock and explosive dynamic loads due to terrorist acts and other emergency situations affecting the construction structures of critical buildings and structures of oil and gas facilities. An example of such impacts is the recent terrorist attack on the Nord Stream gas pipelines. Due to the large number of parameters affecting the physical process of deformation of structures with this type of impact, experimental research is currently an integral part of scientific research in this area. Such studies are especially relevant for reinforced concrete structures, which, on the one hand, are very widely used in construction, and on the other, have a complex nonlinear nature of deformation. To conduct experimental research, it is necessary to design and implement specialized stands, with the help of which it is possible to create a short-term dynamic effect on the structure. A review of the literature data has shown that test stands based on drop-weight stands are most often created for conducting such studies. In such stands, the energy of a falling load is used to destroy structures. It follows from the above that the design and improvement of stands for research of reinforced concrete structures on the effect of short-term dynamic loads is an urgent task of practical importance. The purpose of the work is to describe the structures of the test stands created on the basis of the drop-weight stand in the laboratory of the Reinforced Concrete and Stone Structures Department, Tomsk State University of Architecture and Building, to identify their main advantages and indicate disadvantages; as well as to state further development paths in the field of design and implementation of such stands. Methods: theoretical analysis of literature and Internet sources, modeling, experimental research. Results. Various modifications of test stands based on a drilling rig for research of reinforced concrete structures have been designed and implemented. The main advantages and disadvantages of such stands are shown and further ways of their development are formulated.

On the basis of theoretical and experimental studies, the prerequisites and the method of calculation of bent and compressed-curved reinforced concrete structures with zone reinforcement made of steel fiber, working under static and short-term dynamic loads, are formulated. In the developed method for calculating the strength of normal and inclined sections, a nonlinear deformation model is implemented, which is based on the actual deformation diagrams of materials. The developed calculation method is brought to the program of calculation of reinforced concrete structures with zone reinforcement of steel fiber under short-term dynamic loading, taking into account the inelastic properties of materials. The numerical studies made it possible to determine the influence of various parameters of steel-fiber reinforcement on the strength of reinforced concrete elements. To confirm the main results of the developed calculation method, experimental studies of reinforced concrete beam structures reinforced with conventional reinforcement and a zone steel-fiber layer are planned and carried out. Experimental studies were carried out under static and short-term dynamic loads. As a result of the conducted experiments, data were obtained that characterize the process of destruction, deformation and cracking of steel-reinforced concrete elements under such types of loading. The dependences of changes in the energy intensity of reinforced concrete structures with zone reinforcement made of steel fiber in the compressed and stretched cross-section zones under dynamic loading are obtained. The effectiveness of the use of fiber reinforcement of normal and inclined sections of bent and compressed-curved elements to improve the strength and deformative.
