Improvement of the Structural Solution of Monolithic Reinforced Concrete Floors with the Use of Steel Profiled Flooring

Abstract

Steel profiled flooring as a formwork reinforcement has been successfully used in far-abroad countries in the erection of high-rise buildings with a steel framework. However, there is scarcity of research on this topic at the moment, and there is little to no experience in the use of such structures in low-rise construction, which is important for earthquake-prone regions. The use of steel framework in the erection of low-rise buildings leads to the increased consumption of steel. This research reflects the analysis of the use of steel profiled flooring as formwork reinforcement for a monolithic reinforced concrete floor; their advantages and disadvantages for various structural systems are described. The paper suggests using a new design of the reinforced concrete purlin for the use in such floors; in addition, it presents ways of achieving the combined action of concrete, flooring, and slab with the purlin, which have been verified by means of experiments and calculations.
