It is vital to monitor and keep track of damage on bridge structures due to multiple mechanical, environmental, and traffic-induced factors. Monitoring the formation and propagation of structural damage is also pertinent for enhancing the service life of bridges. Bridge Health Monitoring (BHM) has always been an active research area for engineers and stakeholders. While all monitoring techniques intend to provide accurate and decisive information on the remaining useful life, safety, integrity, and serviceability of bridges; maintaining the uninterrupted operation of a bridge highly relies on understanding the development and propagation of damage. BHM methods have been extensively researched on bridges over the decades, and new methodologies have started to be used by domain experts, especially within the last decade.  Emerging methods, as the products of the technology advancements, resulted in handy tools that have been quickly adopted by bridge engineers. State-of-the-art techniques such as LiDAR, Photogrammetry, Virtual Reality (VR) and Augmented Reality (AR), Digital Twins, Computer Vision, Machine Learning, and Deep Learning are now integrated part of the new-generation BHM operations. This paper presents a brief overview of these latest BHM technologies.","PeriodicalId":44437,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Bridge Engineering","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83672848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Arkansas Department of Transportation replaced the existing historical structure, which was costly to maintain and considered structurally deficient. The new iconic structure consists of two basket-handled 134 m tied-arch bridges which are designed to accommodate 24 000 vehicles daily and includes a shared-used path. The US$98 million bridge was completed in 2017. Located along the existing alignment in a downtown metropolitan area, impacts to traffic were a prime concern. The bridge was closed to traffic for 6 months to allow for construction and to float the new arches into place. Throughout design, fracture critical members were given careful consideration. The tie-girder was designed with a bolted connection to prevent a fracture in one plate from propagating throughout the cross-section. It was then analysed as a three-sided section at the extreme event limit state. This internal redundancy minimised the potential risk of a catastrophic structural failure. This paper discusses the design considerations for the fracture-critical members, the construction technique, and the expected movement of the main-span tied-arch superstructures.","PeriodicalId":44437,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Bridge Engineering","volume":"148 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88648148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interactions between the flow around this bridge and two existing bridges adjacent to the new bridge had the potential to create large scour holes. Since the original bridge would need to remain open during construction, a scour study was performed to determine the placement of the piers. The new bridge uses prestressed concrete bulb tee girder spans for the approaches and one 160.6 m (527 foot) steel network tied arch for the main navigation span. The bridge was designed in 2008 and was one of the first modern tied arch bridges that used internal redundancy for fracture critical members using bolted angles at the intersection of the tie girder webs and flanges in the United States. Due to vertical clearance constraints, the tied arch contains a framed-in-floor system to minimize structure depth. This also required a specific slab pouring sequence to relieve the elongation effects of the tie girder during construction. This signature structure opened to traffic in 2012 and project completion occurred in summer of 2013. This paper focuses on the pier placement relating to the scour concerns and the design of the tied arch span.","PeriodicalId":44437,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Bridge Engineering","volume":"106 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81014549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seismic assessment of such structures is of great importance, particularly for high-seismic regions. Hence, this study assesses the seismic performance of Veresk masonry arch bridge, the longest masonry arch bridge of Iranian railway network (a span length of 99 m), spanned over a valley of depth 110 m, through a reliable sensor-based model updating. Dynamic tests are carried out using a test train, composed of 6-axle locomotives and 4-axle freight wagons, which travels across the bridge, and subsequently, vibration response of the instrumented bridge is measured. A high-fidelity 3D Finite Element (FE) model of the bridge is developed and updated using the measured vibration characteristics: mid-span displacements and natural frequencies. Finally, the seismic performance assessment of the bridge is performed through non-linear static and dynamic analyses for two seismic hazard levels with return periods of 150 and 1000 years. It is found that for the hazard level with a return period of 150 years, both nonlinear static and dynamic analyses give very similar results. However, for the seismic hazard level with the return period of 1000 years, the results of the static analysis are more conservative.","PeriodicalId":44437,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Bridge Engineering","volume":"13 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82240028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aerodynamic studies were traditionally carried out in wind tunnel facilities, but there are now greater opportunities for using computational fluid dynamics modelling. Few studies of three-dimensional aerodynamic simulations of lightweight vehicles on bridges exist but there has been limited validation and verification work done to date. In the study reported in this paper, three-dimensional computational fluid dynamics models were developed for the Queensferry Crossing cable-stayed bridge in Scotland, containing wind shields and sample vehicles. The models considered the wind effects from a range of yaw wind angles and subsequently determined the aerodynamic coefficients of vehicles. The models were verified by means of a mesh sensitivity study, a domain sensitivity study and comparisons with wind-tunnel test results. The models were then validated by using the same modelling process with a different type of wind shield, and again comparing results with wind-tunnel test data for the same configuration. Results demonstrated that the modelling can determine the aerodynamic coefficients to a similar level of accuracy to that of wind tunnel tests.","PeriodicalId":44437,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Bridge Engineering","volume":" 35","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72382802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes the innovative construction methods adopted for building the bridge safely and efficiently in an extremely challenging marine environment, which leveraged on the extensive use of the Design for Manufacture and Assembly (DfMA) solutions with most of the bridge elements above the sea level being prefabricated or precast offsite. This includes the construction of the 10,000 tonnes steel arch bridge, which was fully prefabricated near Shanghai, then transported to Hong Kong by a semi-submersible barge, and eventually erected onto the piers by using the float-over method. In addition, most of the concrete decks, piers and the pile cap shells were precast offsite and then lifted into position on site. This project holds a number of engineering records in Hong Kong, including the longest arch bridge, the first-time adoption of S690QL high-strength steel for major bridge elements and the largest-scale implementation of the float-over erection method.","PeriodicalId":44437,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Bridge Engineering","volume":"1995 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87552817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
