Three types of self-piercing riveting (SPR) joints, i.e., steel/aluminum, carbon fiber reinforced polymer (CFRP)/ aluminum, and aluminum/aluminum, were constructed using three different top sheet materials with the same aluminum alloy as bottom sheet. The effects material on joint quality mechanical behavior evaluated. materials’ characteristics dominate rivet piercing process consequent interl...

Fiber reinforced polymer (FRP) laminates are being successfully used for strengthening of existing reinforced concrete structures. Bond of the FRP reinforcement to the concrete substrate is of critical importance for the effectiveness of the technique. In this project, flexural test specimens were prepared to address some of the factors expected to affect bond, namely, bonded length, concrete s...

This paper explores the use of Carbon fiber reinforced polymer (CFRP) material for strengthening of steel bridges. The research work includes an experimental program to study the effectiveness of using very small diameter CFRP strands, configured in a sheet format, for strengthening of steel structures. The experimental program includes scaled steel-concrete composite beams strengthened with th...

This research investigates the behavior of extended reinforced concrete beams that have been enhanced using CFRP at extension points. Five with measurements 2500 mm in length, 150mm width, and 260mm height were built different types. The studied cases included varied strengthening schemes for splice joints. findings conclude inclusion horizontal stirrups on complete top beam produced comparable...

It is an effective way to improve the flexural behavior of reinforced concrete (RC) members by externally bonded carbon fiber reinforcement polymer (CFRP) laminates on the soffit of the members. However, there is little investigation on flexural performance of RC beam flexurally strengthened by side-bonded FRP laminates. To investigate the flexural behavior of RC beams side-bonded CFRP laminate...

This manuscript studied the effect of U-CFRP wrapped sheet anchorage on flexural performance unbonded post-tensioned PC members subjected to partial strand damage and strengthened using CFRP Near-Surface Mounting techniques. The program includes six girders as a control girder, girder with 14.2%, four by laminates NSM technique without anchorages. testing results show that 14.2% has reduced str...

This paper reports the effects of carbon fiber-reinforced polymer (CFRP) length on the failure process, pattern and crack propagation for a strengthened concrete beam with an initial notch. The experiments measuring load-bearing capacity for concrete beams with various CFRP lengths have been performed, wherein the crack opening displacements (COD) at the initial notch are also measured. The app...

The purpose of this study was to understand the deflection behavior reinforced concrete beams using GFRP bar as flexural reinforcement and sheet shear reinforcement. tested with dimensions span length were 3000 mm, width 150 mm height 250 quality f'c.25 MPa. use 3D13 U-wrap 50 wide a distance 100 mm. is only installed in spans. beam loaded two concentrated loads monotonically until it collapses...

In the application of multiple Carbon Fiber-Reinforced Plastic (CFRP) plates onto a structural steel member, stepping of the CFRP plate ends is often adopted to prevent debonding. This approach requires the nonuniform extension of CFRP plate lengths. In this study, to shorten the length of CFRP plates, a nonuniform overlapping arrangement of several CFRP plate ends was proposed and the theoreti...
