Loading simulation on 60 m truss bridge using weigh in motion data.

Bridge design in Indonesia adhere to the regulations outlined in SNI 1725:2016, the Bridge Loading Standard. Under this standard, vehicle loads are currently represented as idealized forms of the actual loads they impose. Recent technological advancements have enabled the real-time measurement of vehicle loads as they traverse bridges, providing a more accurate representation of the actual loads experienced. Weigh-In Motion (WIM) technology, consisting of sensors installed on bridge elements, captures the responses of these elements to traffic loads. The primary objective of this research is to assess the characteristics of actual traffic loads, generate traffic load simulations using WIM data, and conduct a comparative analysis between the actual traffic loads derived from WIM data and the planned traffic loads specified by SNI 1725:2016. This study utilized WIM data collected from the Kaligawe Bridge in Semarang and simulated its application on a 60 m span simple steel frame bridge using the Monte Carlo method. The comparative analysis of the internal force values derived from WIM data against those planned according to SNI 1725:2016 revealed that the internal force ratios ranged from 86% to 97%. These findings indicate that the actual traffic loads measured through WIM technology on the Kaligawe Bridge result in lower internal forces compared to the standard loads specified in SNI 1725:2016.
