Investigate the Effect of Replacing the Traditional Reinforcing With Steel Stirps in Two-Way Concrete Slabs

Abstract

This study analyzes the effect of employing steel strips as a new reinforcing method in two-way concrete slabs rather than the traditional approach of steel bar reinforcements. The study includes the casting of two slabs with self-compacting concrete and evaluating them under uniform load. The proposed reinforcing technique is used for first slab, and the traditional reinforcing method is used for the second slab. Both styles of reinforcing method used the same equivalent amount of steel. Significant observations in behavior were recorded throughout the research process in ultimate load, first crack load and important computation was done about stiffness and energy absorption. Furthermore, new analytical equations proposed to compute the amount of steel strips that required for design the suggested method of reinforcement. The ultimate load of the panel with steel strips was 106 kN while the panel with bar reinforcements was 144.5 kN. In spite of lower ultimate load but proposed style of reinforcement shows more absorb energy 1399 joule than traditional style which was 610 joules at service load.
In projects focused on sustainability, steel strips could be a preferred option despite the lower load resistance, especially when green building standards or environmental certifications are important.
The outlook of the proposed reinforcing technique refers to open the way for the huge questions that may eventually – with more improvements – lead to change the reinforcing method of two-way concrete slabs.
