Buckling of trapezoidal steel deck wall with local load on the support: A review

This review article evaluates the existing literature on the calculation and strength of thin-walled elements or steel deck. It is noted that among the publications, there are no works that would consider the dependencies between the parameters of the deck and its strength under local load. Methodology. This article examines a number of open-source studies on the calculation of thin-walled elements using various methods: normative, analytical, and numerical. The influence of the width of the deck support, the thickness of the flooring wall, and the angle of inclination of the deck wall on the bearing capacity of its wall under local load is considered. The study is based on the method of partial coefficients and the direct method, as well as the numerical calculation of the section of the profiled flooring in the ANSYS software package. Results and Discussion. A review of the sources showed that various methods for calculating thin-walled elements have their advantages and disadvantages. Calculations have shown that the thickness has the greatest effect on the stability of the flooring wall. As the thickness of the wall increased, the force of loss of stability increased from 201 to 559.7%, depending on the technique. Conclusion. All the calculation methods used give similar dependencies of the strength of the deck wall on its parameters. The numerical calculation showed that the load‑bearing capacity is 1.07 to 2.25 times greater compared to other methods. This must be taken into account in the numerical calculations of steel deck.
