In order to make the bridge finite element model more accurately and effectively reflect state of real bridge, this paper uses dynamic response on-site structural vibration frequency static load strain, proposes a method combining forces construct objective function for optimal analysis. The approach structure Yihe Super Bridge has been corrected. By using “ANOVA” find out significant parameter...

Bridge deck inspection is essential task to monitor the health of the bridges. This paper reports the data collection and analysis for bridge decks based on our novel robotic system which can autonomously and accurately navigate on the bridge. The developed robotic system can lessen the cost and time of the bridge deck data collection and risks of human inspections. The advanced software is dev...

Deck inclination and vertical displacements are among the most important technical parameters to evaluate the health status of a bridge and to verify its bearing capacity. Several methods, both conventional and innovative, are used for structural rotations and displacement monitoring; however, none of these allow, at the same time, precision, automation, static and dynamic monitoring without us...

this paper identifies eleven types of asphalt pavement distress types, commonly occuring in tehran metropolitan area. of these, five distresses namely: corrugation; utility cut depression ;pot holes; alligator cracking; and loss of bridge deck surfacing are rather common. however, others namely: shear failure; shrinkage cracks; lane joint cracks; bleeding; and shoulder distress are less prevail...

High performance concrete (HPC) bridge decks are prone to premature cracking if movement is restrained. Internal curing (IC) can reduce shrinkage cracking in concrete structures, thus improving their performance and service life. However, there is very limited information available in the literature on the possible extension of service life due to internal curing. This paper addresses this ques...

A stochastic model of traffic excitation on bridges is developed assuming that the arrival of vehicles traversing a bridge modeled as an elastic beam follows a Poisson process, and that the contact force of a vehicle on the bridge deck can be converted to equivalent dynamic loads at the nodes of the beam elements. The parameters in this model, such as the Poisson arrival rate and the stochastic...

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...
