The complexities and costs associated with preserving the nation’s bridge infrastructure demand innovative approaches to analysis of data and prediction of future bridge conditions. Several Bridge Management systems (BMS) have come into existence following the ISTEA act of 1991. The policy analysis module of BMS systems developed is restricted to analytical methods. With the availability of mod...

It is essential to construct structural health monitoring systems for large important bridges. Zhijiang Bridge is a cable-stayed bridge that was built recently over the Hangzhou Qiantang River (the largest river in Zhejiang Province). The length of Zhijiang Bridge is 478 m, which comprises an arched twin-tower space and a twin-cable plane structure. As an example, the present study describes th...

Due to the location and environment of Taiwan, the frequency of nature disaster is high and the caused damages to the human life, properties and transportation facilities are serious. Considering the disaster prevention of bridge structures caused by earthquake, scour, debris flow, corrosion and senescence, literatures involving the developed bridge management information systems and the bridge...

High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

Due to the growing number of structurally deficient bridges in the United States, methods for determining the structural performance of in-service bridges is vital to the preservation of the nation’s bridge network. By utilizing field testing, the response of the bridge due to a known traffic load can be assessed, and more accurate structural performance can be determined. The objective of this...

Recent experimental research has shown that ordinary unbounded steel reinforced elastomeric bearings (SREBs) can be considered as an attractive cost-effective option for the seismic isolation of highway bridges. To further investigate its benefits, the current study is focused on the seismic risk assessment of an optimally designed highway bridge isolated by SREB system. A typical three-span hi...
