Comparative analysis of the calculation results of steel-reinforced concrete slabs with profiled sheeting
Incoming article date: 14.08.2025When constructing reinforced concrete floors on profiled steel sheeting, it is possible to significantly reduce the construction time and provide simple and convenient support units. The article discusses the standard methods for calculating composite reinforced concrete floor slabs with profiled sheeting according to SP 266.1325800.2016. A series of calculations were performed using ultimate forces and a nonlinear deformation model (NDM), and a comparison was made with experimental data. The data obtained indicate a significant overestimation of the bearing capacity for a number of samples calculated using the NDM method. This indicates the need to change the approach to NDM calculations and the need to make adjustments to the σ-ε calculation diagram for profiled steel sheeting, reflecting the actual operating conditions of the element.
