Overview

Experimental study demonstrates enhanced flexural resistance in damaged concrete beams using near-surface mounted bars, suggesting anchor bolts increase peak capacity and reduce deflection.

Key Points

  • Anchor bolts coupled with two glass fiber-reinforced polymer bars significantly enhance peak load-carrying capacity and improve member ductility while minimizing mid-span deflection.
  • Experimental evaluation of reinforced concrete beams analyzed the load-deflection response across varying bar lengths, end anchorage conditions, and concrete cover bonding techniques.
  • Supports using near-surface mounted bars with end anchorage to restore flexural resistance, showing that end cover bonding is far more critical than bonding at the maximum moment zone.
