INVESTIGATION OF THE CAPABILITIES OF NUMERICAL MODELING FOR THE DESIGN OF STEEL-CONCRETE CONNECTIONS BASED ON EXPERIMENTAL STUDIES OF FOREIGN RESEARCHERS

This article presents a numerical study of the shear head (SH) joint in reinforced concrete-steel structures using the ANSYS software package. The relevance of using reinforced concrete-steel structures in the construction of multi-story buildings and infrastructure projects is due to their high strength, cost-effectiveness, and durability. However, the use of monolithic slabs with reinforced concrete columns is limited by construction complexity and architectural constraints. The aim of the study is to verify the reliability of results obtained in previous experiments and assess the accuracy of the finite element method for calculating shear joints. The study is based on the work of D.V. Bompa and A.Y. Elgazuli, which focused on the analysis of the connection between a steel column and a reinforced concrete slab. The results of the numerical modeling showed a high degree of convergence with the experimental data (up to 98%) and confirmed the feasibility of using the finite element method for accurately predicting the behavior of SH joints under various loads. The study also identified some limitations of the model, which require further refinement and a more detailed consideration of material properties to improve calculation accuracy. The findings can be used for optimizing the design of reinforced concrete-steel structures and enhancing their reliability in construction practice.
