Despite the recent developments in structural health monitoring, there remain great challenges for accurately, conveniently, and economically assessing the in-service performance of the main cables for long-span suspension bridges. A long-term structural health monitoring technique is developed to measure the tension force with a conventional sensing technology and further provide the in-servic...

Structural analysis and construction control of staged-construction processes are major subjects in the context modern long-span bridges. Although forward backward methods able to simulate situations, their main disadvantage is that they usually apply stage superposition principle. In actual process, due changes made plan, process needs be adjusted at any time, it difficult implement complete a...

For most existing bridges, supporting continuous traffic loads is the basic function. However, in addition to this load, bridges are exposed to environmental (Frangopol and Soliman, 2015 [1]), as well as various other complex loads, that are mostly random in nature, such as earthquake, flow-included loadings, wind and so on. All these loading conditions need to be considered and must satisfy th...

Aimed at the health monitoring and evaluation of bridges based on sensing technology, the monitoring contents of different structural types of long-span bridges were defined. Then, the definition, classification, selection principle, and installation requirements of the sensors were summarized. The concept was proposed that new adaptable long-life sensors could be developed by new theories and ...

Abstract Compared with acceleration-based modal analysis, displacement can provide a more reliable and robust identification result for output-only analysis of long-span bridges. However, the estimated displacements from acceleration records are frequently unavailable due to unrealistic drifts. Aiming at obtaining accurate stable results determining parameters, this study develops multi-rate we...

We study the periodic solutions of equations with asymmetric nonlinearities ``at resonance'' with the Fuc @ k spectrum. We compute the associated topological degree and prove existence, multiplicity, and stability of large-amplitude oscillations for equations with a small friction term. Such equations can be viewed, e.g., as simple models for investigating vertical oscillations of long-span sus...

Recently, an increase in the number of construction of long span bridges like a cable-stayed bridge has necessitated the development of technologies for long-term maintenance works and safety of vehicles using such bridges. A lot of researches on application of cutting-edge IT technologies and robotics in the civil engineering field have been conducted for better operation and maintenance of a ...
