Abstract

Intelligent digital methods for extending the service life of the Nibelungen Bridge

To extend the service life of structures while maintaining their structural safety and functionality, effective monitoring and maintenance concepts are necessary. Within the scope of the Priority Program 2388 “Hundred Plus – Extending the Service Life of Complex Structures through Intelligent Digitalization” (SPP 100+), funded by the German Research Foundation (DFG), interdisciplinary methods including digital models, digital linkages, and condition indicators, have been investigated and validated on the Nibelungen Bridge in Worms. First, two structural health monitoring systems and their combination are described in detail, with particular focus on the fusion of accelerometer data. Subsequently, innovative data-driven simulation methods are presented to determine the complete temperature field of the bridge superstructure. In addition, various numerical solutions covering different element types and levels of detail are introduced. Finally, methods for managing knowledge about the bridge's condition are presented. The methods were developed relatively independently of each other and validated at the NBW. In the next step, all methods will be integrated to support the maintenance of the NBW.

延长尼伯龙根大桥使用寿命的智能数字方法

延长尼伯龙根大桥使用寿命的智能数字化方法为了延长结构的使用寿命，同时保持其结构安全和功能，需要有效的监测和维护概念。在由德国研究基金会（DFG）资助的2388优先项目“百+ -通过智能数字化延长复杂结构的使用寿命”（SPP 100+）的范围内，研究了包括数字模型、数字链接和状态指示器在内的跨学科方法，并在Worms的Nibelungen大桥上进行了验证。首先，详细介绍了两种结构健康监测系统及其组合，重点介绍了加速度计数据的融合。随后，提出了创新的数据驱动模拟方法来确定桥梁上部结构的完整温度场。此外，还介绍了涵盖不同元素类型和细节级别的各种数值解决方案。最后，提出了管理桥梁状态知识的方法。这些方法的开发相对独立，并在NBW上进行了验证。下一步，将整合所有方法，以支持NBW的维护。
