A health monitoring system was designed and installed on Dafosi Bridge, the largest cable-stayed bridge across the Yangtze River in western China. This article briefly describes an online deflection monitoring system, the most important sensing subsystem of the health monitoring system. It can be divided into two major components, one for measurement, and one for control and data processing. Th...

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 ...

Design optimization of cable-stayed bridges is a challenging optimization problem because a large number of variables is usually involved in the optimization process. For these structures the design variables are cross-sectional areas of the cables. In this study, an efficient metaheuristic algorithm namely, momentum search algorithm (MSA) is used to optimize the design of cable-stayed bridges....

The current paper describes the development and implementation of a vision system in the context of the monitoring of a cable-stayed bridge, discussing the major requirements, the cost of the instruments, the particular aspects of the developed image processing algorithms, the integration in a conventional monitoring system and the results of application to the International Guadiana Bridge in ...

The structural health monitoring system (SHMS) provides an effective tool to conduct full-scale measurements on existing bridges for essential research on bridge wind engineering. In July 2008, Typhoon Fung-Wong lashed China and hit Sutong cable-stayed bridge (SCB) in China. During typhoon period, full-scale measurements were conducted to record the wind data and the structural vibration respon...

Abstract Cable-stayed bridges are important infrastructure facilities serving the world today. Therefore, their safety against earthquake ground motions is crucial. However, due to long spans, affecting seismic excitations might be spatially non-synchronous. This paper presents a study of effect non-synchronous on Aswan cable-stayed bridge located at southern Egypt. Nonlinear time history analy...

Abstract Many researchers have carried out experimental and numerical investigations to examine building structures’ response explosive loads. Studies of bridges subjected blast loads are limited. Hence, in this study, we present a case study on cable-stayed bridge, namely, Charles River Cable-Stayed Bridge-Boston, assess its robustness resistance against the progressive collapse resulting from...
