Composite Bridge Deck

In this paper, a new cost-effective composite bridge deck consisting of multiple steel box cells, concrete slab, and glass fiber-reinforced polymer layer is investigated. First, the structural performance of the deck under static loading is evaluated experimentally. Then the results are validated by a finite element program. Results of the numerical analysis are in good agreement with those of the experiments. The load–displacement relationship, ultimate flexural resistance, failure mode, neutral axis, and strain distribution on glass fiber-reinforced polymer layer and concrete slab are examined during the test. Final results revealed that the ultimate failure of the composite deck initiates by longitudinal cracking on the top surface of the concrete slab. No debonding occurs at the interface between concrete slab and steel boxes which indicates that perfobond ribs could be effectively used for shear connection. The results of experimental and numerical analysis demonstrated that the bridge deck possesses desirable strength and meets the stiffness requirements.

High Performance Composite

Today’s new high performance composite materials can be engineered to meet specific and critical needs in modern cities and industries. Fiber Reinforced Polymer (FRP) is considered to be the best alternate material for manhole covers as it has longer life span and has the capability to withstand heavy load. The invention related to Strengthening of precast concrete manhole cover by using fiber composite. Three sample of circular manhole cover were constructed for this experimental test program. Two different strengthening schemes were used in this paper. Sample 1 includes strengthened control slabs and other two were strengthened with Glass Fiber Reinforced Polymer (GFRP) Laminates. The strengthening of manhole covers was done with different layers of GFRP wraps. This is why investigation was undertaken to increase the durability of precast concrete covers. The high effectiveness of fiber reinforcement enhancing the load bearing capacity of concrete covers was investigated.

Frp Bars

A new type of HFRP hybrid bars (hybrid fiber reinforced polymer) was introduced to increase the rigidity of FRP reinforcement, which was a basic drawback of the FRP bars used so far. Compared to the BFRP (basalt fiber reinforced polymer) bars, modification has been introduced in HFRP bars consisting of swapping basalt fibers with carbon fibers. One of the most important mechanical properties of FRP bars is compressive strength, which determines the scope of reinforcement in compressed reinforced concrete elements (e.g., column). The compression properties of FRP bars are currently ignored in the standards (ACI, CSA). The article presents compression properties for HFRP bars based on the developed compression test method. Thirty HFRP bars were tested for comparison with previously tested BFRP bars. All bars had a nominal diameter of 8 mm and their nonanchored (free) length varied from 50 to 220 mm. Test results showed that the ultimate compressive strength of nonbuckled HFRP bars as a result of axial compression is about 46% of the ultimate strength. In addition, the modulus of elasticity under compression does not change significantly compared to the modulus of elasticity under tension. A linear correlation of buckling load strength was proposed depending on the free length of HFRP bars.
