“…It further details the relationship of compressive and tension members, that is, the measurement from the top and bottom chord. Dissimilar characteristics of the model versus measurement approach and anomalous validation coefficients [48] disclose a poor connection between structural members and lower structural stiffness, prompting extensive evaluation [6,48]. The mean of the measured results is presented in Table 3 with their respective residuals and validation coefficients.…”

The present study assessed the Bailey Bridge’s condition and investigated its adaptation as a permanent structure, targeted the Acrow Bailey Bridge in Japan. Field diagnostic loading experiments were performed under various loading conditions, such as dynamic and static loading tests. The onsite data were obtained using a transducer, friction strain gauge, target measurements for the image processing approach, and accelerometer. From the field measurements, the deflection and stresses of the bridge were found to operate within the linear elastic region. The bridge was then accurately modeled based on the in situ geometric configuration of the bridge, and Finite Element Analysis was performed. The model’s accuracy was validated with the onsite data under the linear elastic domain. The model was deployed to check for resistance of critical members. A nonlinear analysis based on the linear and nonlinear buckling method was performed to determine the subject bridge’s Serviceability Limit State and Ultimate Limit State. The results showed that the first out-of-plane eigenvalue buckling analysis could monolithically assess bridge members. Further, the study established digital twin models resolve for historical data through in situ modeling measurements. Therefore, the findings obtained in this study highlight the bridge’s Structural Health Condition, bearing capacity, and propose a framework for adaptation as a permanent structure.

This research models a sustainable development through a serious game. The sustainable development system is influenced by internal factors and external factors. Internal factors consist of three sub-systems, namely: Culture, structure and technology. External factors consist of three sub-systems, namely: environment, economic actors and socio-cultural actors. The model in this research is agent-based involving three types of agents (firm, worker, and policy), internal variables, and external variables using a dynamic system. The behavior of each variable is observed using a dynamic system model. By providing initial values in internal factor variables and external factor variables, agent movement can provide information about the firm-size condition, the income of workers and the effect of policy on the development of companies and workers. Determination of initial data from internal factor variables and external factor variables aims to achieve a balance between supply and demand. In a certain phase, it will produce an optimal value, shown by supply and demand are at the same point. This condition needs to be maintained by adjusting all input variables so that supply and demand are in an optimal position.

“…[1]. One common assessment method for existing bridges is load testing [2], [3], and static load testing is an effective method for assessing the performance of bridges, understanding the actual operational conditions of the bridge, and identifying existing issues promptly to improve and optimize bridge quality [4], [5]. Load testing also serves as a crucial starting point for monitoring operations.…”

To accommodate the rapid development of residential and commercial areas in the Bumi Serpong Damai (BSD) Region, Banten, the construction of the Kadisurung bridge is necessary to integrate road networks. Before being operational to ensure the safety of bridge users, load testing is conducted. Parameters that must be met in the testing include not exceeding the strain and deflection limits during operational conditions, including when maximum loading occurs. To assess the bridge's performance during operation, research was conducted on both sides of the central span (western side bridge, JSB, and eastern side bridge, JST) with static load testing carried out with gradually increasing loads up to 50% UDL (136 tons), followed by gradual load removal. At JSB, the maximum deflection at 100% UDL, estimated from the deflection at 50% UDL, was 39.92 mm, and at JST, it was 31.67 mm, while the allowable deflection was 43.3 mm. Based on the deflection parameters, the relative capacities of JST and JSB are expressed as 108.5% and 136.7% respectively, relative to their allowable capacities. This indicates that the estimated bridge capacity using static load testing parameters is 6%-10% greater than when using parameters from dynamic load testing. Thus, the bridge is deemed suitable for operation.
