Development of Concrete Slabs by Using Hollow Core Action Integrated with Profiled Steel Sheets: State of the Art Review

다국어 초록 (Multilingual Abstract)

Improving the structural performance and sustainability of slabs has been a major concern through the journey of research, due to the economic, self-weight, structural and environmental advantages that could be obtained, especially in high-rise buildings. Therefore, the challenge was to design lighter-weight and sustainable slabs either by modifying the cross sections or by using light-weight concrete. This paper discusses and compares the properties, experimental, analytical and numerical studies that were conducted on the structural behavior of two types of slabs: Hollow core slabs and Composite slabs. Hollow core slabs contain longitudinal voids of various shapes with the aim of reducing the self-weight by average of 40%. On the other hand, composite slabs consist of concrete and steel sheets of different profiles, that is known for its superior ultimate load that exceeds by almost 90%. However, Hollow core slabs integrated with profiled steel sheets amalgamate both longitudinal voids in the concrete and steel sheets, which in result combine the properties of both of them. This is the first paper that discusses voided composite slabs in the light of previous research by reason of the tremendous economic and structural enhancements that could be attained.
