Reduction in Stress and Deformation in Rectangular Slab by using NBD Fibre Strips Instead of CFRP

Slabs, A shallow i.e. having depth very less to other dimensions reinforced-concrete structural member that is very wide compared to depth spanning between beams, girders & columns. Concrete slabs are widely used for floors, roofs & bridge decks. When a slab is supported on four sides with reinforcing bars is called a two-way slab. Those slabs are generally designed by empirical methods. This is a fine & cost effective structural system. The slab will deflect in both directions, and the loads on the slab are transferred to all supports. There are different types of two-way slabs. The two way slabs are further divided to 3 different systems: flat plates, flat slabs, & two-way beam-supported slabs. The simplest type of two-way slab is known as a flat plate. This type of slabs is supported directly by the columns. Column spacing typically ranges from 15 to 25 ft with minimum slab thicknesses of 0.5 to 0.83 ft for live loads of about 2.5 kPa. Drop panels are added at the columns for longer spans. These types are known as a flat slab and have an economical span range of 25 to 30 ft with minimum slab thicknesses of 0.70 to 0.83 ft. In this report a Rectangular slab is modeled using a 3D modeling software called SOLIDWORKS. Computer based analysis software called ANSYS is used to perform the deformation tests of various Rectangular slabs with or without openings. The 3D model of the Rectangular slabs is imported to ANSYS software to carry out the Finite Element modeling. Meshing is done using ANSYS software. Also change the CFRP strips material with NBD material to reduce the cost of the product. Because of the cost of NBD material is very less as compared to the CFRP material. And also drop in stress and deformation in the RC slab.
