The extensive construction of bridge health monitoring (BHM) systems has made it challenging for the authorities to manage them centrally. reliable operational status BHM is vital obtaining accurate data and evaluating condition bridges. To evaluate these systems, this study established an assessment model that integrates triangular intuitionistic fuzzy analytic network process (TIFANP) comprehensive evaluation (TIFCE) method. Firstly, index system was a system. Factors such as stability, reliability, maintenance, early warning, human-computer interaction were comprehensively considered. Secondly, indicator weights assigned using TIFANP. rating levels divided into four grades, membership non-membership functions indicators constructed based on TIFCE. Finally, effectiveness proposed method verified case study. This first time suitable in-service been proposed. results show TIFANP better accounts relationships non-independence interactions among indicators. Hesitations in decision-making quantified, making weight allocations more accurate. outperforms other comparison methods can be used scientific objective manner.

BOPVis: Bridge Monitoring Data Visualization for Operational Performance Mining

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(15), P. 6615 - 6615

Published: July 29, 2024

Bridges are fundamental facilities in the transportation system, and their operational performance is crucial for economic social development. Many large bridges now equipped with structural health monitoring (SHM) systems that collect various types of real-time data. However, our user study found despite accumulation massive amounts data, current analysis methods cannot efficiently process large-scale, high-dimensional To address this, we have developed BOPVis, a visualization system bridge BOPVis allows users to intuitively locate sensors extract corresponding data from 3D digital model bridge. It also provides convenient flexible interactions examining trends over time correlations across hundreds channels. A real-world long-span suspension China used as case demonstrate advantages mining. Through global temperature deformation behaviors explored align physical mechanism documented SHM literature. The its interactive capabilities, offers new method analyzing

Experimental and Numerical Analysis of an Innovative Combined String–Cable Bridge

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(17), P. 7542 - 7542

Suspension bridges, such as stress-ribbon, are among the simplest structural bridge systems and have lowest height. The flexibility of these elegant bridges poses great challenges for designers to minimize their deformability under asymmetrical operational loads. Due small initial sag, load-bearing structures also cause significant tensile forces, which requires them large cross-sections massive anchor foundations. This paper analyzes an innovative suspension steel structure combined with a string cable. More attention is paid asymmetric loading this more relevant structures. new studied numerically experimentally. It established that stabilizes displacements loading. stabilization efficiency proportional value pre-tension force string. obtained results reveal behavior enable evaluation accuracy numerical results, well applied modeling. In addition, experimentally allow aspects bridge, will be useful in further studies type
