The article highlights the current state of the problem and analyzes the constructive and organizational and technological solutions used in the construction of lightweight reinforced concrete structures. The process of creating effective building systems is directly related to the technology of their implementation, since technological limitations often become a key factor affecting the feasibility of implementing certain engineering solutions. It is known that even the most innovative design concepts may remain unrealized due to the lack of appropriate technological support or the economic efficiency of their production. In this regard, the improvement of lightweight reinforced concrete structures should occur in close connection with the development of progressive technological processes aimed at ensuring the rational use of materials, reducing the dead weight of structures, and increasing their operational reliability. One of the promising areas is the use of hollow inserts that are not removed after the concrete hardens. Such elements allow you to shape the internal geometry of structures, ensuring a reduction in material consumption and weight characteristics without reducing the load-bearing capacity. The use of such solutions requires a comprehensive approach, which includes: development of optimal structural parameters taking into account the geometric and mechanical characteristics of the inserts; numerical modeling of stress-strain processes to assess the effectiveness of the application of such technologies; economic feasibility analysis, which allows determining the balance between material costs and the resulting technical effect. Thus, the introduction of the latest technologies for manufacturing lightweight reinforced concrete structures is a promising direction that contributes to increasing the efficiency of construction production and the development of modern design methods.
