This study explores the application of accelerometer sensors for structural health monitoring (SHM) in evaluating the performance of polypropylene fiber-reinforced composites (PFRC). Incorporating polypropylene fibers into concrete enhances its structural integrity and durability. However, accurately assessing PFRC behavior under various conditions is crucial for its practical application in construction. This research employs advanced accelerometer sensor technology for real-time monitoring and assessment of PFRC performance. Experimental investigations captured and analyzed the dynamic response and structural behavior of PFRC specimens subjected to loading conditions of 200 kN, 400 kN, 600 kN, 800 kN, and 1000 kN. Accelerometer sensors, strategically placed on the surface of PFRC cubes, cylinders, and beam elements with 1% fiber content, provided precise data on vibration, deformation, and stress distribution, enabling a detailed evaluation of mechanical properties and durability. Frequency versus conductance graphs plotted from the accelerometer data offered valuable insights into the material’s behavior, highlighting its mechanical properties and response characteristics under different stress levels. The findings contribute significantly to structural engineering and materials science, particularly in SHM and PFRC applications, supporting advancements in the design, construction, and maintenance of resilient infrastructure systems.
