Abstract

The use of precast prestressed concrete girder bridges in Indonesia has been increasing rapidly due to their high quality, reliability, and faster construction on site. The girder components are typically designed for a specific bridge span and can be prefabricated. The Directorate General of Highways of the Ministry of PUPR (Bina Marga) has released a standard design for prestressed concrete girder bridges with a typical span of up to 40 m. This design is based on the bridge loading standard SNI 1725 2016, which determines the live traffic load through consensus due to limited data on actual traffic load measurement results. However, the Ministry of PUPR has been implementing actual traffic load measurements using weigh-in-motion (WIM) technology to directly measure the load of passing vehicles. In this study, a risk assessment of the failure risk of a standard Bina Marga bridge with a 40-m span prestressed concrete girder type was conducted based on B-WIM load measurements. The results of this assessment indicate that the standard Bina Marga bridge has a failure risk of 1.48 x 10-4, which is smaller than the acceptable risk of failure according to the AASHTO LRFD Bridge Design Specification as referenced in SNI 1725 2016.

B-WIM 荷载测量下的 Bina Marga 标准设计预应力混凝土梁桥失效风险评估

预制预应力混凝土梁桥因其质量高、可靠性强、现场施工速度快等优点，在印度尼西亚的使用量迅速增加。梁构件通常是为特定跨度的桥梁设计的，可以预制。由于实际交通荷载测量结果的数据有限，该标准通过协商一致的方式确定实际交通荷载。然而，PUPR 部一直在使用移动称重 (WIM) 技术实施实际交通荷载测量，以直接测量过往车辆的荷载。在本研究中，根据 B-WIM 荷载测量结果，对一座跨度为 40 米的预应力混凝土梁型标准 Bina Marga 桥进行了失效风险评估。评估结果表明，标准 Bina Marga 桥的失效风险为 1.48 x 10-4，小于 SNI 1725 2016 中参考的 AASHTO LRFD 桥梁设计规范可接受的失效风险。
