Implication

Experimental and numerical methods reveal CFRP grids enhance cracking load in concrete one-way slabs, indicating effective reinforcement strategies.

Key Points

This research aims to examine the flexural behavior of concrete one-way slabs reinforced with CFRP grids.
Conducted experimental tests on eight concrete one-way slabs, seven with CFRP grids and one with a steel grid.
Varied test parameters including concrete strength grade, grid size, and concrete cover thickness.
Developed and validated a finite element model to simulate and compare against experimental findings.
CFRP grid-reinforced slabs showed significant deformation without failure.
Increasing concrete strength grade resulted in a 64.1% rise in cracking load from C20 to C40.
Reducing concrete cover thickness from 30 mm to 10 mm enhanced serviceability load capacity by 44.9%.
The finite element model exhibited good alignment with experimental results.
