The paper presents the results of a study of the effectiveness of aerodynamic windproof devices. Considered various options for the placement of wind protection relative to the deck and simulated wind speed and air movement trajectory. As a result of the analysis of the velocity fields, the best layout options for wind-proof devices have been proposed.
Facilities for the storage of nuclear fuel are distinguished from other objects by high standards of safety in any operating conditions. A feature of these structures is the large thickness of the walls and floors. This feature should be taken into account in the calculations of seismic effects and thermal stresses caused by uneven temperature fields in concrete. In the work, calculations of joint effects on the building of thermal stresses and earthquakes are made. The calculations allowed us to distinguish the features of the deformation of concrete structures.
Facilities for storing radioactive waste with residual heat differ from other facilities in high safety standards in all operating conditions. A feature of these structures is the presence of biological protection in the form of walls and ceilings made of reinforced concrete with a large thickness. The combination of heat dissipation and the large thickness of walls and floors create conditions for the appearance of significant thermal stresses. This feature should be taken into account in the strength calculations of these buildings, taking into account the summation of seismic effects, gravitational forces and thermal stresses caused by uneven temperature fields in concrete. The paper presents the results of calculations of the combined effects of thermal stresses and earthquakes on a building. The data obtained made it possible to determine the features of the deformation of concrete structures with a combination of loads.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
