The Comparison of Condition Evaluation of Siak II Steel Frame Bridge between the FCM Method and the Bridge Management System

Abstract

An accurate bridge condition evaluation system is the main factor of a bridge maintenance management. The Government of Indonesia has a bridge evaluation guide based on Australian rules namely the Bridge Management System. In this method, a visual field check is performed to determine the value of the bridge condition and then analyzed by using the bridge management information system program (sim-ibms) through a technical screening process. By using this method, it can be determined several actions are needed to be reported that the bridge is safe or damaged. But this method has been used for 25 years by Indonesia. Nowadays, research and methods are developed to evaluate the condition of bridges, such as the Fracture Critical Member (FCM) method. This method can directly measure displacement through computer programs based on the traffic volume. The evaluation conducted in two ways such are numerical methods with computer programs and visual bridge surveys. Numerical analysis is performed to estimate the critical elements of the bridge which will then evaluated visually. This research aims to compare the condition evaluation of steel frame bridge of Siak II regarding the level of damage and bridge repairing period to obtain appropriate maintenance.

An Intelligent Bridge Management and Maintenance Model Using BIM Technology

“…Apriani and Megasari defined BIM technology and established the frame system combined with the life cycle project. is frame system is used to design reinforced concrete bridge columns [9]. Xia et al used BIM technology to formulate extensible bridge information mode in designing bridge engineering and construction, mainly including parametric modeling, digital prototype, SD simulation, and 4D model.…”

Damage Prediction of the Steel Arch Bridge Model Based on Artificial Neural Network Method

“…A method of monitoring a bridge is needed to predict at any time so that maintenance can be done early and prevent sudden collapse. Bridge condition assessments developed Several techniques, such as BMS and Fracture Critical Member (FCM) [3,4]. However, the method has not shown satisfactory results because people cannot monitor the real conditions of bridge structure behaviour in detail.…”
