Assessing structural health of ultra high-performance fiber reinforced concrete pedestrian bridges through OMA and FEM integration

Integrating Operational Model Analysis with Finite Element Model yields an effective instrument for concurrently evaluating the stability of a building. In contrast to Finite Element Model, which relies on computational models to simulate and compare dynamic behaviours, Operational Model Analysis de...

Integrating Operational Model Analysis with Finite Element Model yields an effective instrument for concurrently evaluating the stability of a building. In contrast to Finite Element Model, which relies on computational models to simulate and compare dynamic behaviours, Operational Model Analysis derives dynamic characteristics from a bridge's responses to external vibrations. This research assesses the Ultra High-Performance Fibre Reinforced Concrete pedestrian bridge located in Klang, Selangor, using both techniques. This paper examines Operational Model Analysis techniques with weak sources of excitation and compares experimental results with Finite Element Model results to address the knowledge gap. In addition to employing a Finite Element Model, this analysis incorporates modal parameters that were acquired through ambient vibration experiments. This research explores the practicality and dependability of Operational Model Analysis in demanding scenarios by comparing experimental findings to Finite Element Model. The findings indicate that there are notable variations in natural frequency between the two approaches both before and after model upgrades. There is a strong correlation between the Operational Model Analysis and Finite Element Model since the mode shapes obtained by both models are very similar. Moreover, the initial frequency of vertical bending that EN1991–2:2003 approved following the model update fits within the permitted range. The results provide insight into the performance characteristics of Ultra-High-Performance Fiber-Reinforced Concrete pedestrian bridges and the technique used for modal analysis. © 2024 Institution of Structural Engineers
