Dynamic Behavior of Reinforced Earth Walls: A frequency Based Investigation
Dynamic Behavior of Reinforced Earth Walls: A frequency Based Investigation
As urban development advances into seismically active territories, the design of retaining structures capable of reliably withstanding earthquake-induced forces necessitates the integration of material efficiency and sustainability considerations. In pursuit of this objective, A comprehensive experimental program utilizing 1g shaking table tests was conducted to elucidate the response characteristics of modular block faced geosynthetic-reinforced walls under variable seismic inputs. The investigation spans a range of seismic excitation frequencies ranging from 2.5 Hz to 10 Hz and intensities 0.1g and 0.5g to simulate realistic earthquake conditions. The research delineates the nonlinear response of reinforced systems under variable seismic demand. The experimental results reveal that the maximum acceleration amplification factor consistently occurs at the crest of the wall and increases under near-resonant conditions. By analysing the acceleration amplification patterns under varying excitation regimes, the study uncovers key soil structure interactions. These outcomes advocate for the incorporation of performance-based design frameworks for urban geotechnical systems, promoting infrastructure resilience against earthquake hazards. In alignment with the United Nations Sustainable Development Goals, this study contributes to the development of resilient and resource-efficient infrastructure systems.
