Abstract
This article examines methodological approaches for experimental studies of loadbearing behavior in thick reinforced concrete slabs (without shear reinforcement) with varying tensile zone reinforcement characteristics. A critical analysis of regulatory standards (SP 63.13330, Eurocode 2, ACI 318, Model Code 2020) reveals their inconsistency with experimental data when the shear spanto-effective depth ratio is ≤2.0. Through comparative analysis of domestic and international research practices and numerical simulations, the study establishes justification for test specimen parameters to investigate strength, crack formation, and failure mechanisms under punching shear. The developed loading methodology ensures punching effect generation in the support zone, complemented by comprehensive stress-strain monitoring techniques during incremental loading stages.
