Strengthening of Prism Beam by Using NSM Technique with Roots Planted in Concrete

Abstract

This paper presents experimental results of four prismatic concrete reinforced beam and strengthened by NSM (Near surface mounted) FRP (Fiber Reinforced Polymer) reinforced technique, with additional roots planted in the concrete. The strengthening technique causes load capacity of beams to increase from (6%-8%).A decrease in mid-span deflection was also observed from (4%-5%).Using this technique gave increasing in flexural beam resistant under the same conditions and this increasing was also noted in shear beam resistant.

Enhancement of the Shear-flexural Strength of the Rubberized Concrete Prism Beam by External Reinforcement

“…For strengthening prism by fiber-reinforced polymer that the type of FRP has been used Sikadur-300 Product as present in Table 1. Concrete prism is grinded to make a rough surface for perfect bonding between fiberreinforced polymer with concrete prism [20] (see Figure 4).…”
