Flexural Behaviour of Concrete Oneway Slabs Reinforced with Hybrid FRP Bars

摘要

This paper focuses mainly the flexural response of concrete one-way slabs reinforced with Hybrid FRP (Combination of Glass FRP and Carbon FRP) bars. It also deals with the interaction of design parameters, to examine some of the critical issues and challenges that arise while designing Hybrid FRP slabs to satisfy ultimate strength and serviceability criteria using the ACI 440.1R-03 Guide. The insufficiency of design standards is a significant stumbling block for the extensive use of fibre-reinforced polymers (FRPs) in reinforced concrete (RC). The sole pivot of this paper is to concentrate on the properties of concrete and reinforcement in different aspects and finally the flexural behaviour of the slabs has been analyzed experimentally and analytically. Two point static loading has been adopted to study the flexural behaviour. A finite element software ANSYS is used to analyse the flexural behavior of the slabs. Cracking and deflection of Hybrid FRP reinforced concrete structures are prudently studied. A general non-linear procedure found on slip and bond stresses, is adopted for the prediction of cracking and deflections.
