A precast reinforced concrete (RC) T-beam located in seaport Terminal Peti Kemas (TPS) Surabaya built in 1984 is used as a case study to test the accuracy of non-destructive test techniques against more traditional bridge evaluation tools. This bridge is mainly used to connect the berth in Lamong gulf and the port in Java Island for the logistic purposes. The bridge was retrofitted 26 years into its life by adding two strips of carbon fiber reinforced polymer (CFRP) due to excessive cracks observed in the beams. Non-destructive field measurements were compared against a detailed finite element analysis of the structure to predict the performance of the girder in terms of deflection and moment capacity before and after the retrofitting work. The analysis was also used to predict the long-term deflections of the structure due to creep, crack distribution, and the ultimate moment capacity of the individual girder. Moreover, the finite element analysis was used to predict the deflection behavior of the overall bridge due to vehicle loading. Good agreement was obtained between the field measurement and the analytical study. A new service life of the structure considering the corrosion and new vehicle demand is carried out based on field measurement using non-destructive testing. Not only are the specific results beneficial for the Indonesian port authority as the stakeholder to manage this structure, but the approach detailed also paves the way for more efficient evaluation of bridges more generally over their service life.

栈桥的长期性能:以印度尼西亚海上港口结构为例

案例研究使用了位于1984年建造的泗水码头Peti Kemas(TPS)港口的预制钢筋混凝土(RC)T型梁,以比较传统的桥梁评估工具来测试无损测试技术的准确性。该桥主要用于连接拉蒙湾的泊位和爪哇岛的港口,以用于物流。由于在横梁中观察到过多的裂缝,通过添加两条碳纤维增强聚合物(CFRP)条对桥梁进行了26年的翻新。将非破坏性现场测量结果与结构的详细有限元分析进行比较,以预测在改造前后的梁在挠度和弯矩承载力方面的性能。该分析还用于预测由于蠕变引起的结构的长期挠度,裂纹分布,以及单个大梁的极限弯矩能力。此外,有限元分析被用来预测由于车辆载荷引起的整个桥梁的挠曲行为。现场测量和分析研究之间取得了良好的一致性。在无损检测的基础上,根据现场测量结果,考虑了腐蚀和新的车辆需求,实现了结构的新使用寿命。特定的结果不仅对作为利益相关者的印度尼西亚港口当局有利于管理这种结构,而且详细的方法还为在桥梁的使用寿命内更有效地评估桥梁铺平了道路。有限元分析被用来预测由于车辆载荷引起的整个桥梁的挠曲行为。现场测量和分析研究之间取得了良好的一致性。在无损检测的基础上,根据现场测量结果,考虑了腐蚀和新的车辆需求,实现了结构的新使用寿命。特定的结果不仅对作为利益相关者的印度尼西亚港口当局有利于管理这种结构,而且详细的方法还为在桥梁的整个使用寿命内更有效地评估桥梁铺平了道路。有限元分析被用来预测由于车辆载荷引起的整个桥梁的挠曲行为。现场测量和分析研究之间取得了良好的一致性。基于无损检测的现场测量结果,考虑了腐蚀和新的车辆需求,实现了结构的新使用寿命。特定的结果不仅对作为利益相关者的印度尼西亚港口当局有利于管理这种结构,而且详细的方法还为在桥梁的使用寿命内更有效地评估桥梁铺平了道路。基于无损检测的现场测量结果,考虑了腐蚀和新的车辆需求,实现了结构的新使用寿命。特定的结果不仅对作为利益相关者的印度尼西亚港口当局有利于管理这种结构,而且详细的方法还为在桥梁的整个使用寿命内更有效地评估桥梁铺平了道路。基于无损检测的现场测量结果,考虑了腐蚀和新的车辆需求,实现了结构的新使用寿命。特定的结果不仅对作为利益相关者的印度尼西亚港口当局有利于管理这种结构,而且详细的方法还为在桥梁的整个使用寿命内更有效地评估桥梁铺平了道路。
