description: The purpose of the dissertation is to analyze the stress-strain state of metal structures. Mathematical optimization methods, variational methods, structural mechanics, and the finite element method implemented in software complexes were used to achieve this goal. The focus of this work is on developing an optimization algorithm that can reduce construction costs by minimizing efforts in the structure or its individual elements. Stress-strain state regulation of the structure is an optimization method widely used in both building design and reconstruction. The following tasks were addressed in this study: 1. Development of a method for determining the optimal prestress in rod structures; 2. Proof of the optimality of the prestress obtained using the developed method; 3. Development of an algorithm for determining optimal edge loads using the LIRA CAD software package; 4. Solving optimization problems for steel rod structures; 5. Technical and economic comparison of two variants of frame buildings. The paper includes a review and analysis of domestic and foreign literature, regulatory documents, and methods for solving optimization problems. It was concluded that this topic is relevant and requires further detailed investigation. As a result, a method for determining the optimal prestress has been developed and an algorithm for determining edge loads using a software package has been implemented. The developed algorithm enables to make the design optimal during design stage and can help in finding solutions during the reconstruction of the building. Examples are provided to illustrate the effects of prestressing on structural elements and the overall frame. Through technical and economic calculations, it was determined that the economic benefit derived from increased usable area exceeds the additional costs of construction. By effectively managing the stress-strain state of building structures, it is possible to reduce the cost of construction projects. Various information technologies, including software, cloud services, databases, and others such as LIRA SAPR, Mendeley, and eLibrary.RU, were used in this study.
