Vibration model test and seismic performance evaluation of polypropylene fiber reinforced concrete lining of mountainside tunnels in Loess Plateau
Researchers have developed a new seismic performance evaluation method for polypropylene-fiber-reinforced concrete (PFRC) used in mountain-adjacent tunnels. The study found that a 0.9% fiber content significantly improves concrete strength and seismic energy dissipation.
Why it matters
Provides critical engineering insights for improving infrastructure resilience against earthquakes in mountainous regions like the Loess Plateau.
