| The bridge's inspections need to create a high-resolution process for more effective monitoring of new and existing concrete structures. Over time, the deteriorating conditions of highway bridges vary: damage may be the direct result of earthquakes, repetitious loads causing fatigue failure, high overloads, chemical attacks, traffic impacts or environmental hazards.; In recent years, Fiber Optic Sensors have received significant attention throughout the world and especially in the field of Civil Engineering. FOBG Sensors are useful in detecting and inspecting the measurement of environmental parameters such as strain, crack, deflection, pressure, temperature, vibration, chemical concentration and electromagnetic field.; The objective of this research is to develop a now method of assessing the strain and cracks of concrete bridge by using Fiber Optic Bragg Grating Sensors. This was embedded in concrete structures to detect and monitor the strain and crack.; The research consisted of an experimental program and experimental results. In the experimental program, concrete specimens were cast and tested to determine concrete mechanical properties, strains and cracks. |
