“…Since their results were based on four days of data collected during summer, the interesting findings of this study are not necessarily indicative of the general thermal behaviour of the bridge. Probably the most comprehensive study on steel bridges to date in this field involved the use of finite element heat transfer analysis and field monitoring data to investigate the temperature distribution and thermal response of the Tsing Ma Bridge (suspension, 1377 m main span) in Hong Kong (Xia, Chen, Bao, & Xu, 2010;Xia, Chen, Zhou, & Xu, 2012;. Due to significant differences between the climates of Asian and European countries, the thermal performance results reported from studies on bridges in Asia might not be directly applicable to European bridges.…”

Suspension Bridge using a wireless sensor networkA study on the thermal performance of the Tamar Suspension Bridge deck in Plymouth, U.K., is presented in this paper. Ambient air, suspension cable, deck and truss temperatures were acquired using a wired sensor system. Deck extension data were acquired using a two-hop wireless sensor network. Empirical models relating the deck extension to various combinations of temperatures were derived and compared. The most accurate model, which used all the four temperature variables, predicted the deck extension with an accuracy of 99.4%.Time delays ranging from 10 minutes to 66 minutes were identified between the daily cycles of the air temperature and of the structural temperatures and deck extension. However, accounting for these delays in the temperature -extension models did not improve the models' prediction accuracy. The results of this study suggest that bridge design recommendations are based on overly-simplistic assumptions which could result in significant errors in the estimated deck movement, especially for temperature extremes. These findings aim to help engineers better understand the important aspect of thermal performance of steel bridges. This paper also presents a concise study on the effective use of off the shelf wireless technology to support structural health monitoring of bridges.

“…It was strongly suggested that the nonuniform temperature distribution brought about by solar radiation should be considered in the design of curved bridges. Xia et al [46], for the first time, investigated the temperature distribution in a long-span suspension bridge-the 2132-m-long Tsing Ma Bridge-through finite element analysis. With appropriate assumptions, the bridge was divided into deck plate, section frame, and bridge tower, as shown in Figure 6.…”

Thermal load is an important factor that must be taken into account during the procedure of bridge design and structural condition evaluation especially for those statically indeterminate bridges and cable-supported bridges. This paper presents an overview of current research and development activities in the field of thermal load in bridge, in which emphasis is placed on the thermal load models established by numerical analysis and field measurement. The theoretical formulations and boundary conditions of heat transfer in bridge are firstly outlined. And then, the states of the art of numerical solutions for temperature distribution in bridge including finite difference method and finite element method are reviewed in detail. Following that, the progress on thermal load in three types of representative bridges that are concrete bridge, steel-concrete composite bridge, and steel bridge based on field measurement data is discussed extensively. Finally, some existing problems and promising research efforts about thermal load in bridge are remarked.

“…Temperature has critical influence on the behavior of cable-stayed bridges, in particular long cable-stayed bridges and long suspension bridges [8,79]. Cao et al [12] comprehensively introduced the temperature distribution on girder, towers, and cables of a cable-stayed bridge and the behaviors of this bridge under temperature.…”

Cable-stayed bridges are a type of long-span bridges that have been extensively constructed throughout the world. However, cable-stayed bridges suffer from a variety of performance deteriorations and natural disasters during their service time. Structural health monitoring, having emerged since the early 1990s, is regarded as an in situ field experimental technique to understand the behaviors and performance of real, full-scale bridges under real loadings and environmental conditions and to further ensure the safety, serviceability, durability, and sustainability of bridges. In this paper, the existing various monitoring technologies for cable-stayed bridges developed are overviewed. The design approaches of structural health monitoring systems for cable-stayed bridges are introduced. The data analysis, modeling, and safety evaluation of cable-stayed bridges based on structural health monitoring technology are addressed. The applications of structural health monitoring technology for cablestayed bridges are summarized. The design code for structural health monitoring systems is described for large highway bridges (including cable-stayed bridges) that are authorized by the Ministry of Transportation in China. Finally, this study discusses the challenges and future trends in structural health monitoring technologies for cable-stayed bridges, particularly for data-driven science and technology in structural health monitoring field.
