Abstract

This paper presents a comprehensive study on the utilization of accelerometer sensors for structural health monitoring (SHM) in the assessment of polypropylene fiber-reinforced concrete (PFRC) performance. The incorporation of polypropylene fibers into concrete has shown promising potential in enhancing its structural integrity and durability. However, the accurate evaluation of PFRC behavior under varying conditions remains a critical aspect in ensuring its practical application in construction and infrastructure. In this research, I focus on employing advanced accelerometer sensor technology for real-time monitoring and assessment of PFRC performance. A series of experimental investigations have been conducted to capture and analyze the dynamic response and structural behavior of PFRC specimens subjected to different loading conditions as 200 kN, 400 kN, 600 kN, 800 kN & 1000 kN. The accelerometer sensors, strategically placed on the surface of the PFRC concrete with 1% of Fiber in Cubes, Cylinders and Beam elements provide precise data regarding vibration, deformation, and stress distribution, enabling a detailed evaluation of its mechanical properties and durability. Through these experiments, the dynamic response and structural behavior of PFRC under varying loading conditions were thoroughly investigated. Subsequently, frequency vs. conductance graphs were plotted using data obtained from the accelerometer sensors. The analysis of these graphs provided valuable insights into the material behavior, highlighting its mechanical properties and response characteristics under different stress levels. The outcomes of this investigation offer significant contributions to the field of structural engineering and material science, particularly in the domain of SHM and the utilization of PFRC. The findings serve as a basis for further advancements in the design, construction, and maintenance of resilient and sustainable infrastructure systems.
