Performance Assessment integrating Bridge monitoring and CSI Modelling

Abstract

Abstract

Brides are an important part of any transport systems network which connects roads and villages with cities. Many Iraqi bridges remain in poor condition even after inspection and confirmation that they are of acceptable standards due to the role played by various risk factors, including traffic volume and insufficient capacity. Effects of changed patterns of operational loads, slack, deterioration, and other man-made effects on bridge construction causes its degeneration. The main purpose of this research was to determine the structural condition of the superstructure of the Barboty Bridge and any associated damage, if any, utilizing strain, displacement sensors and CSI Bridge software. CSIBridge was employed to generate the finite element model of the bridge super structure. The difference between the experimental and analysisresults was extracted to be about 10.60 %, which represents good agreement. Deflections, distribution factors, modal curvature, and rating factor classification were extracted. All these parameters were found under AASHTO specifications with no abnormal condition observed.
