This paper reviews the structural performances of reinforced concrete beams and slabs filled with lightweight materials to identify the research gaps in the area for future research development. Data is extracted from the research works done by different researchers. It was then recomputed to analyze the effects of concrete replacement regions, geometrical properties and spacing of lightweight materials on the ultimate strength of the structural elements. The lightweight materials were found to be more effective in reducing the weight of the slab without significantly affecting its strength as compared with the beam. The lightweight materials are recommended to have round corners, spaced out and positioned at the neutral axis or the compressive region for better strength performance so that the effective strength to weight ratio exceeds 1.0.

“…It has been recorded that the performance of buildings with HCRC slabs are not good due to the premature failure of floor in the structural test and highlighted the need of further research in this area [6]. Many researchers have evaluated the capacity of hollow core slab in terms of flexure [5][6][7] web shear [4,5], fire resistance [8], seismic resistance [6,9], torsion [10] and many more, using different formats of hollow core slab systems. The hollow slab provided with PVC pipes and styrophoam, to create cavity in the slab, failed in shear instead of flexure while reducing self-weight up to 24% [7].…”

Experimental Study on the Structural Behavior of Cast in-situ Hollow Core Concrete Slabs

et al. 2020

An experimental work has been carried out to study the flexural behavior of cast in-situ hollow core reinforced concrete (HCRC) slabs constructed by using easy, cost effective and implementable techniques in field. The precast elements made of different easily available affordable material i.e. concrete, polyvinyl chloride (PVC) and plaster of paris having voided cross- sections of circular, rectangular and triangular shapes were incorporated in one direction during pouring of concrete with minimum flexural reinforcement to construct HCRC slabs. A total of 14 slab specimens including 02 specimens per specification were tested with third point loading for the assessment of flexural behavior as per ASTM standards C78/C78M. The flexural behavior of HCRC slabs with polyvinyl and plaster of paris elements having hollow cross-sections was comparable with the control solid slabs, however, HCRC slab with concrete pipes showed 7 to 8 percent reduction in flexural strength with 19 to 20 percent reduction in self-weight. All the tested specimens performed well in shear as no shear failure was observed. This study reveals that HCRC slabs with locally available material having hollow cross section elements can be used for the construction of cast in-situ monolithic construction of one-way slabs with ordinary construction techniques.

“…When such a structure is projected as a horizontal component, its flexural performance is critical under uniformly distributed loads. In recent years, many studies on mechanical behavior have been conducted on cast-in-situ two-way voided slabs and other composite structures, with the essential goal of applying environmental systems to residential buildings [15][16][17][18][19][20][21][22][23]. These analytical, numerical, and experimental studies compared with studies on traditional hollow slabs (reinforced concrete waffle slabs and cellular flat plates), show significant demonstrable improvements in structural performance, void filler material, and cost savings.…”

Behavior of a Two-Way Lightweight Steel–Concrete Composite Slab Voided with Thin-Walled Core Boxes towards Sustainable Construction

et al. 2020

View full text Add to dashboard Cite

High-performance engineered structural systems are crucial for sustainable development in the field of construction. In our previous research, a novel steel–concrete composite beam with transverse and longitudinal hidden girders exhibited good flexural behavior and desirable ductility. However, there is a dearth of studies on the flexural response of a steel–concrete composite slab voided with thin-walled core boxes. Therefore, in this study, we investigated the overarching flexural mechanism of the proposed structure when subjected to uniform vertical loads. The experimental detection results illustrated that the deflection value of the composite beam was 95.75% less than the GB/T 50152-2012 recommendation. Numerical results further validated this observation. The recorded data from the strain profile at the mid-span of the frame girder indicated that there was a considerable membrane effect, which delayed the strain growth of rebars, yielding appreciable bearing capacity. Thus, two original approaches to predicting the ultimate load of this novel structure are proposed, considering limit analysis using the upper-bound method and the membrane effect, with the latter closely linked to the experimental results. The findings can promote the extensive application of similar sustainable systems and inspire further advancements in advanced engineering structures.
