Seismic Performance of Fiber-Reinforced Concrete Structures

Fibre-reinforced concrete structures have emerged as a robust solution to enhance earthquake resilience in reinforced concrete frames. The inclusion of discrete fibres within the concrete matrix bridges cracks, modifies post-cracking behaviour and increases both ductility and energy dissipation. Under seismic loading, conventional concrete elements often fail in brittle shear, especially at beam–column joints, risking sudden collapse. Fibre additions—from steel to synthetic polymers—improve crack resistance, redistribute stresses and permit reduced transverse reinforcement without compromising safety. Advances in ultra-high performance concrete and high-performance fibre-reinforced cementitious composites extend strength and ductility, enabling slender designs with superior seismic resilience. Globally, these materials are incorporated into retrofit strategies and performance-based design frameworks, delivering improved joint integrity, enhanced hysteretic response and sustainable material utilisation.

The graph below shows the total number of articles in seismic performance of fiber-reinforced concrete structures across all publications each year (not limited to Nature Index journals).

Technical terms

Fibre-reinforced concrete: Concrete containing dispersed fibres (steel, synthetic or natural) to improve tensile strength, crack bridging and ductility under load.

Ductility: The capacity of a material or structure to undergo significant deformation before failure, essential for absorbing seismic energy.

Energy dissipation: The ability of a structure to absorb and dissipate cyclic load energy, often quantified by the area within hysteresis loops.

Hysteresis: The phase lag between cyclic loading and response in a material or element, indicative of damping and energy-absorbing behaviour.

Beam–column joint: The intersection region of beams and columns in reinforced concrete frames, typically the critical zone for seismic damage initiation.
