Finite Element Modeling and Analysis of Hybrid Plate System
Abstract— This paper presents the non linear response of hybrid plate system consist of Fiber Reinforced Polymer (FRP) and ferrocement act as shell for core Reinforced Concrete (RC) by using ATENA-3D software based on Finite Element Method (FEM). In this investigation, the load displacement response of RC plate system with internal stiffened beams was carried out in the first phase and in the second phase of study, analysis of different hybrid plate system reinforced with unidirectional basalt, unidirectional carbon and bidirectional glass fiber fabric as well with ferrocement sheet was presented. Hybrid plate system with unidirectional carbon sheet exhibited the maximum load carrying capacity. Also formation of cracks in the different plate systems was monitored and all systems failed in flexure with formation of cracks on positive moment region.

I. INTRODUCTION
Now days, corrosion is the main concern in Reinforced Concrete (RC) structures. To overcome this problem, Fibre Reinforced Polymer (FRP) composite sheets are the best solution in structural elements as strong and light material. FRP is a composite material made by combining two or more materials to give a new combination of properties. FRP composite is a two-phased material and is composed of fiber (e.g., E-glass, carbon, and aramid) and polymer matrix (e.g., epoxy, polyester, and vinylester resins, which are bonded at interface. FRP materials were widely accepted in infrastructure construction industry during the late 1980s and throughout the 1990s [1]. In general, strengthening techniques with FRP systems can be used to enhance the ductility as well as the flexural and shear capacity of all structural elements (i.e. columns, beams, slabs, structural walls), bridge components (i.e. piers, girders, decks). FRP application in construction sector is gaining attention in India after the Gujarat earthquake occurred in 2001[2]. Most of the experimental as well numerical work was done on Carbon Fibre Reinforced Polymer (CFRP) and Glass Fibre Reinforced Polymer (GFRP), very little attention has been given on recently developed Basalt Fibre Reinforced Polymer.
