Experimental study of reinforced concrete piles wrapped with fibre reinforced polymer under vertical load

Abstract

This research mainly focuses on the nature of Fiber-Reinforced Polymers (FRP) wrapped piles for the axial compression load. Normally, the degradation of Reinforced Cement Concrete (RCC) structures occurred due to corrosion, inadequate quality materials, aging, live load increments, fatigue, damages and deterioration, and so forth. RCC pile foundations are commonly affected by the above reasons. So, these structures can be strengthened with suitable methods such as jacketing, stitching, overlaying, sealing, grouting, coating, Near Surface Mounted (NSM) systems, FRP wrapping, repairing, and blanketing. FRP wrapping is well suited for strengthening pile structures because of its easy application, and this method is done without using heavy tools and skilled labor. Due to its being non-metallic, FRP reinforcing has desirable properties such as high resistance to chemicals as well as heat, flexibility, large tensile strength, permeability, and also no oxidation. Thus, FRP wrapping was selected as the chosen approach for this ongoing research. In this study, we apply an axial compression load as well as a skin friction condition to a pile member that has been modified to assess its performance and behavior.

Feasibility of Repairing Concrete with Ultra-High Molecular Weight Polyethylene Fiber Cloth: A Comprehensive Literature Review

“…Li et al [152] demonstrated the cracking propagation in small-sized concrete specimens. The development of load-bearing capacity is a significant concern after wrapping FRP cloth around concrete elements [153][154][155]. Campione [156] conducted compressive experiments on concrete prisms wrapped with carbon FRP cloth.…”

Rehabilitation of damaged RC exterior beam-column joint using various configurations of CFRP laminates subjected to cyclic excitations

“…Since it was difficult to foresee the whole load, it was vital to keep the specimen from completely failing. Preloading at this amount was designed to induce severe damage and numerous cracks, but a not complete failure [59]. The specimen was therefore simple to handle, fix, and retest.…”

Shear strengthening of reinforced concrete beams using fibre reinforced polymer composites

“…The combining cutting-edge FRP technologies with ecologically friendly materials like M-sand enhances structural performance and strength while adhering to sustainable construction standards and minimizing the ecological footprint of the sector [17]. The available case studies and analytical techniques, the confinement effects of FRP composites under vertical loading situations were examined while raising the vertical resistance of pile foundations [18]. A study was given on the impact of crushed stone sand, a byproduct of crushed aggregate production -on the mechanical properties of steelfiber-reinforced concrete.…”
