Serviceability predictive model of ultra-high performance concrete bridge using vibration assessment / Siti Shahirah Saidin

The bridge structures are important component in highway, railway, and urban road which contribute to the economy, politics and culture. Bridge are designed to carry and transfer loading from the traffic during its service lives where the load actions are in the form of forces, deformation, acceleration that applied. Many existing old bridges have exceeded their design life, the average age of bridges being more than 50 years old and have failed due to structural deficiencies, unexpected events, excessive load, and ineffective monitoring. Thus, the proper maintenance and monitoring by conducting structural health monitoring (SHM) can be done to reduce the number of bridges from collapse is needed. SHM aims to provide quantitative and reliable data on the real conditions of a bridge, observe its evolution and detect the appearance of degradation.
