Seismic cracking mechanism and control for pre-stressed concrete box girders of continuous rigid-frame bridges: Miaoziping bridge in Wenchuan earthquake as an example
Advances in Bridge Engineering - Tập 2 - Trang 1-25 - 2021
The box girder of the Miaoziping Bridge, a three-span prestressed concrete continuous rigid-frame bridge, suffered a serious crack in its box section’s web near the 1/6 to 1/2 length of the side span and the middle-span length of 1/4 to 3/4, as a result of the 2008 Wenchuan earthquake, which also caused large lateral residual displacements at both ends of the side span. In this study, eight strong......
A yield curvature model considering axial compression ratio
Advances in Bridge Engineering - Tập 4 - Trang 1-20 - 2023
This study proposed a yield curvature prediction model considering axial compression ratio with exponential function which is improved on the basis of the specification effective yield curvature prediction model. Parametric moment–curvature curves approach was used to verify that the yield curvature is greatly affected by the section size, the yield strength of longitudinal steel bar and the axial......
Adding ceramic polishing waste as filler to reduce paste volume and improve carbonation and water resistances of mortar
Advances in Bridge Engineering - Tập 2 - Trang 1-19 - 2021
The use of ceramic waste in concrete/mortar production as aggregate replacement or cement replacement has been under consideration in the last decade to find an effective way to tackle the growing hazard of ceramic waste disposal. In this study, the authors reutilize ceramic polishing waste (CPW) as a filler to replace an equal volume of cement paste in mortar while keeping the mixture proportions......
Vibration response analysis of footbridge based on pedestrian perception
Advances in Bridge Engineering - Tập 4 - Trang 1-27 - 2023
This article aims to study the influence of random crowd loading on the perceived vibration response of pedestrians. Firstly, a vertical vibration response analysis method considering pedestrian perception was established based on the random crowd walking model. Secondly, change rules of maximum vibration response of pedestrians, occurrence time and position interval under different random walk mo......
The influence of vehicle dynamics on the time-dependent resonances of a bridge
Advances in Bridge Engineering - Tập 4 - Trang 1-18 - 2023
In bridge structural health monitoring, the response of the bridge while the vehicle is on the bridge, is called a vehicle-bridge interaction (VBI) response. If the vehicle and the bridge are dynamically coupled, the VBI response depends on the bridge’s and the vehicle’s dynamic properties. Therefore, the damage detection techniques based on the bridge resonances become questionable due to the dyn......
Standardization construction and development trend of bridge health monitoring systems in China
Advances in Bridge Engineering - Tập 1 - Trang 1-18 - 2020
Bridge health monitoring (BHM) technology has been widely accepted as a powerful tool to assess structural performance and has moved from research to practice. Driven by the enormous demand of ensuring bridge safety, the application of BHM technology is particularly active in China and has become an emerging industry in the civil engineering community. It is a common belief among civil engineers t......
Methodology for calculating load capacity reduction and slip relationship of clustered group nail connectorsAbstract Clustered group nail connectors are key connecting components for the full lifecycle construction and safe operation of steel–concrete composite structural bridges. To thoroughly investigate the stress mechanism of clustered group nail connectors in steel–concrete composite structures, this paper conducts a detailed numerical analysis on 100 sets of such co... ...

Experimental study on long friction-type bolted joint combined with interference fit bolt
Advances in Bridge Engineering - - 2024
In recent years, high-strength bolts with friction-type joints have been lengthened to withstand increased traffic load. However, with increase in the joint length, the force able to be resisted by bolted joints has decreased owing to uneven distribution of the bolts within the joint. In addition, the proximity of secondary members to the joint has restricted the allowable size of the splice plate......
A hybrid approach for fatigue assessment of reinforced concrete bridge deck considering realistic bridge-traffic interaction
Advances in Bridge Engineering - Tập 5 - Trang 1-25 - 2024
Reinforced concrete (RC) bridge decks are directly exposed to daily traffic loads and often experience surface cracking caused by excessive stress or fatigue accumulation. The bridge deck fatigue performance over traffic loads needs to be assessed based on accurate dynamic interaction analysis of the bridge and realistic moving vehicles. Most of existing studies on fatigue assessment focus on eith......
Damage control of a twin-column pier with a replaceable steel shear link in a cap beam under transverse seismic motionAbstract This paper proposes a novel twin-column pier with a steel shear link (SSL) installed in the cap beam to reduce seismic damage in the transverse direction. The SSL interrupts the rigid cap beam and relieves the coupled deformation of the two columns. Benefits of the yieldable SSL in the event of a strong earthquake are the longer effective deformation of a c... ...
