The real temperature distribution within 24 h of the main beam in a single-tower hybrid cable-stayed bridge is analysed according to its actual section and material parameters, as well other factors local atmospheric temperature, geographical environment, solar intensity. results show that internal steel–concrete composite uneven, steel higher than at surface concrete slab. Then, finite element...

For the problem of cable damage identification in cable-stayed bridges, we have presented a method for identifying based on deflection monitoring data from small number measurement points. We first describe to reduce analyzed distributional characteristics difference before and after bridges with optimized The derivative is transformed by wavelet transform identify location damaged cable. Then,...

In recent decades, the demand for complex and economical engineering structures with great aesthetics has been on rise cable stayed bridges also take their share of this interest. Besides many advantages cable-stayed are quite flexible, hence susceptible mainly to dynamic actions such as impact loads, wind effects seismic excitations. context, study focused effect A H shape reinforced concrete ...

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 ...

The aim of this paper is to investigate the dynamic response of long span cable-stayed bridges subjected to moving loads. The analysis is based on a continuum model of the bridge, in which the stay spacing is assumed to be small in comparison with the whole bridge length. As a consequence, the interaction forces between the girder, towers and cable system are described by means of continuous di...
