Earthquake-Resistant Joint Buildings: Using Fiber-Reinforced Concrete Material for Earthquake-Resistant Foundations

Earthquake-resistant building structures are designed to withstand seismic forces, minimizing structural damage, human casualties, and economic loss. Achieving earthquake resistance requires not only advanced structural designs but also proper construction techniques, including site selection, foundation reinforcement, and secure structural joints. Flexibility is a key factor in mitigating seismic stress, allowing structures to deform without collapsing. Fiber-reinforced concrete (FRC) has emerged as a promising material for enhancing earthquake resilience, offering improved crack resistance, durability, and tensile strength. This study evaluates the effectiveness of FRC in earthquake-resistant structures using shake table simulations, aiming to develop cost-effective solutions for safer construction in seismic-prone regions. This study evaluated the performance of Controlled Concrete and Fiber-Reinforced Concrete (FRC) with 0.5% and 1% fiber content through Compression and Split Tensile Tests using a Universal Testing Machine (UTM). The Compression Test assessed load-bearing capacity and structural integrity, while the Split Tensile Test analyzed tensile behavior and resistance. Results indicated that Controlled Concrete exhibited superior strength, resilience, and structural integrity compared to fiber-reinforced variations. Although FRC enhanced specific properties such as crack resistance, it did not surpass Controlled Concrete in overall performance. These findings contribute to engineering knowledge for earthquake-resistant foundations, emphasizing the need for further research on fiber reinforcement optimization for structural applications.
