“…This method does not require a fixed viewing position as the tiltmeter is mounted on the bridge directly which greatly increases the measurement efficiency. The results obtained indicate that the rotation method is a potential method for measuring bridge deflection, so that the tiltmeter has significant technical application value and promising future with the approaching results [3]…”

“…The development and successful implementation of long-term structural monitoring systems on bridges have been widely reported by researchers. In recent years, tiltmeters (also called inclinometers) have been widely used for construction monitoring, structural examiners, and long-term performance monitoring of bridges by promoting a simple method at an affordable cost [3][6] [7][8] [9]. The method of measuring bridge deflection using rotational data from the tiltmeter (inclinometer) is considered quite promising, practical, inexpensive, and simple to measure static and dynamic deflection of bridge spans under load, even for bridge spans that cross heights.…”

A bridge is an infrastructure that experiences dynamic and repetitive load for a long period of time, so it is necessary to monitor the condition of the bridge structure to ensure that the bridge is always in a proper condition. This study aims to develop an equation model using multiple regression analysis to establish the relationship between deflection values and rotation values obtained from a PCI girder bridge as a project case study. The results demonstrate that the proposed regression equation accurately estimates the maximum deflection, with an average accuracy rate of 96.4%. The highest level of accuracy is 99.9497 % when the deflection is 0.0606m. The minimum level of accuracy is 86.3821 when the deflection is 0.0346. This result indicated that low accuracy happened at relatively small deflection values of particular load configurations. Thus, this method presents a reliable approach for estimating the maximum deflection based on tiltmeter readings, offering a practical solution with a commendable level of accuracy.

“…A rotational on a support bridge occurs and a deflection in the middle span the bridge. To get the deflection value and the rotation value that occurs on the bridge, field testing is needed [5][6]. To get the deflection value, it can be done by doing a calculation using the rotation value to predict the deflection value [7].…”

A bridge is an infrastructure that experiences dynamic and repetitive loading for a long period, so it is necessary to monitor the condition of the bridge structure to ensure that the bridge is always in proper condition. Deflection is the vertical displacement that can occur in the bridge. This study aims to obtain an correlation model in the form of regression equation with multiple regression analysis methods between the deflection value and the rotation value of the PCI Girder bridge. The analysis was carried out using Finite Element Method software, by modeling the PCI Girder bridge with several vehicle load cases, and the rotation and deflection values of the bridge will be obtained. Several schemes were made regarding the number and location of rotation sensors to determine the level of accuracy. To get the relationship between rotation value and deflection value, a multiple linear regression analysis was carried out. It can be generated a multiple linear regression equation with the dependent variable being the deflection value and the independent variable being the rotation value on the bridge placement. This equation can be used to predict the deflection value in the middle of the bridge span with the percentage difference shows value smaller than 5%. In the analysis, it is able to provide results with the smallest percentage difference between numerical comparison values and linear regression equations.
