Flexural Performance of SCS Sandwich Beam with Foamed Concrete

Abstract:

This paper presents the investigation on the flexural performance of steel concrete steel (SCS) sandwich beam comprising of fibre reinforced foamed concrete (FRFC) as a core concrete, sandwiched between the two steel plates. The steel plates were connected by a J-hook shear connector in order to develop a composite action between the plates and core concrete. The light weight foamed concrete having a density ranged from 1400 to 1450 kg/m³. The SCS sandwich beams were tested under a static gradual loading up to failure to examine its flexural behaviour. The test results revealed that the proposed SCS sandwich beam with FRFC increased the load carrying capacity and ductility performance. The finite element based modelling has also been conducted for the corroboration of test results. A reasonably close agreement has been obtained between the experimental results and predicted values.
