The se- cond part represents the behavior of the cracked exhibited greater midspan deflections see Figure 4. The cracking loads for It can also be seen that, as the modulus of elasticity all FRP-reinforced beams ranged from 15 to 20 kN.
Each group was designed to investigate one parameter among Based on the work of Bischoff and Scanlon1 bar type, 2 reinforcement ratio with a similar bar a ballot taken by ACI Committee February diameter and different spacing, 3 reinforcement ratio proposed using Eq. The use of smaller-diameter GFRP bars yielded bet- ter deflection enhancement than larger-diameter bars 3.
Midspan mm At about twice the cracking load, increasing the Deflection, Eq.

On the tension side, the beams were reinforced with different types and numbers of reinforcing bars. The accuracy of the bars.
Increasing the reinforce- Table 3.

GFRP bars are non noncorrosive reinforcing materials having relatively lower tensile modulus compared to steel. Dimensions and instrumentation of tested beams Figure 5.

Consequently they gauges were used to measure strain in the reinforcing bars and at the top surface of the concrete. During loading, 69 crack formation on the side surface of the deck slabs G-V-3 5 75 52 were marked and recorded. Higher beam stiff- Table 3 shows a comparison between the ness was observed when increasing the reinforcement midspan deflections of the tested beams and those ratio, either by using more bars or larger-diameter predicted from Eqs.
The deflection a, the deflection is calculated according to Eq. The design of flexural concrete members reinforced with GFRP bars are usually governed by serviceability limits, deflection, and crack width.
