The objective of this research project is to optimize the reinforcement of monolithic reinforced concrete slabs to reduce material consumption and labor costs, which is a pressing issue in modern construction. To address this issue, advanced numerical modeling methods were applied using the LIRA-SAPR software suite. These methods include nonlinear finite element analysis (FEA), force redistribution principles, and the concept of variable reinforcement. A methodology for implementing variable reinforcement was developed, based on a detailed analysis of the slab\u27s stress-strain state. The results of numerical experiments demonstrated that the proposed optimization methods, particularly variable reinforcement, can reduce the consumption of reinforcing steel by 12-15% without significantly increasing labor intensity. The significance of this project lies in the development of practical recommendations for construction companies seeking to improve economic efficiency and resource conservation in monolithic construction. This contributes to reducing construction costs and promoting more rational resource utilization
