Abstract
Strengthening of reinforced concrete slabs with fibre reinforced polymers has been an important subject in the present industry. Strengthening is required due to improper maintenance of structures, bad practise of code, heavy loading etc. Strengthening by FRPS is one best methods of retrofitting the slabs due to fact that it works well under the corrosive environment and it increases the service life of a structure. In growing interest for the usage of FRP’S in retrofitting technique, an analytical study is made on the different types of the fibres like Carbon, Basalt, Glass and Polypropylene have been used in strengthening of slabs as well as with different configurations. Finite element package like ANSYS 16 was used for the analysis. In the present study finite element analysis was done for total of nine slabs. Out of which one is control slab and other eight slabs are with four different fibre reinforced polymers material and with two type of configuration. The dimension of the slab used for analysing was (1040X1040X90) mm. Comparison was done with the maximum deflection, principal stress and strain and shear stress and strain for different slabs with different configuration of fibre reinforced polymers.
