... of heavy vehicles compared to other road bridges, deterioration is remarkably advanced. Maintenance costs have continued to rise, while structural safety must still be ensured within limited budgets and personnel. In recent years, research on deterioration prediction using machine learning and using big...

...José António Correia Around 38% of structural damage in metallic bridges occurs due to fatigue, with the aggravating factor being a structural phenomenon unknown until some decades ago, which leads to many existing structures being designed without addressing this process of structural degradation...

...Naomichi Katayama; Chao Lin; Shogo Inadomi; Kenta Itakura; Yu Chen; Pang-Jo Chun This study addresses the challenge of assessing bridge damage progression under compound disasters, specifically focusing on Bridge A in Japan affected by the 2024 Noto Peninsula Earthquake and subsequent heavy...

...Takumi Kobayashi; Kaoru Yoshitani; Michio Ohsumi Post-earthquake bridge inspections are often hindered by the inaccessibility of scaffolding and inspection vehicles, particularly when urgent assessments are required to ensure structural safety and usability. Following the 2024 Noto Peninsula...

...Simone Campos, BSc; Elie Mounzer, PhD Bridges and overpasses are essential structures for mobility and transportation, playinga fundamental role in transportation infrastructure. However, they are susceptible to defectsthat can compromise their safety and durability. Conducting studies on defects...

...Mehdi Rashidi, PhD; Hoda Azari, PhD; John Braley, PhD; Robert Zobel, PhD Understanding the long-term performance of bridges plays a major role in the selection of appropriate asset-management strategies, which eventually reduce life-cycle costs and extend the service life of a bridge. To understand...

...Koji Yamashita; Shingo Tanaka; Takefumi Yamaguchi The Aso Bridge in Japan is located near the Futagawa Fault, which is considered to be the epicentre fault of the Kumamoto earthquake. This paper presents the technical findings obtained through the investigation and design of the Aso Ohashi Bridge...

...Wiryanto Dewobroto A 120 m pedestrian suspension bridge recently inaugurated in Pacitan, East Java, Indonesia, suddenly collapsed when it was empty. It was one of the hundreds of similar bridges constructed through a current government project. Although there were no casualties, finding the cause...

...Meisheng Shi, MSc; Dengguo Li, PhD; Ying Wu, PhD; Pengzhen Lu, PhD The WanJiang Bridge in China was damaged by an oil tanker at 5.28 p.m. on 5 August 2006, and three supporting frames near the mid-span of the bridge, 5# pier, were severely damaged. Some concrete members fell into the river, causing...

...Haoyin Shan, PhD, PE; James Pagenkopf, ME; Kornel Kerenyi, PhD; Chao Huang, PhD The US Federal Highway Administration (FHWA) is developing the next-generation scour programme – that is, NextScour – to improve scour analysis for safe and economical bridge foundation design. NextScour recognises...

...Paul J Vardanega, BE, MEngSc, PhD, GMICE, MASCE, MIEAust, FHEA; Gianna Gavriel, MEng; Maria Pregnolato, MSc, PhD, FHEA Bridge scour is a complex bridge-management problem. It is also a difficult forensic engineering challenge, as the greatest risk occurs during large flows and flood events, when...

...Wei-ming Gong; Zheng-zhen Wang; Guo-liang Dai; Xiao-guang Liu; Ming-xing Zhu; Xin-xin Zhao; Hui Guo Until 20 December 2019, more than 160 bridges have been built or are under construction on the Yangtze River in China, among which 132 bridges span the Yangtze River mainstream. This paper...

...Stéphane Sire; Muriel Ragueneau Among more than 25 000 bridges and viaducts in the French railway network, more than 2000 metallic bridges have been in service for over a century, and they need adapted measures for their maintenance. Due to the increase in rolling speed and axle load...

...Hongjiang Li, PhD The concept of replacement of the closure segment (RCS) emerged originally in a strengthening project for a concrete cable-stayed bridge and was intended to deal with a failure in the closure segment of the main girder. The construction procedure of RCS includes removing...

... the collapse of the structure, two fatalities and injury of 23 (see Figure 4). Figure 4 was taken on the collapse day, and it is possible to observe the P2 column in the background and the Alça Norte (on the left) already without shoring. Figure 4 Alça Sul collapse bridges failure...

...Toshihiko Nagatani; Takeharu Tajiri Repairs were required to a corroded post-tensioned prestressed-concrete continuous-girder bridge that had been in service for over 35 years in the Chuo Expressway in Japan. The work included reinforcing the bridge girders with external cables and partially...

...Kornel Kerenyi; Kevin Flora The Feather River Bridge on Route 20 in Northern California, USA, was damaged by scour during a relatively modest flow event in March 2011. The scour created a hole around the foundation which was nearly 30 feet (9·14 m) deep and which permanently reduced the pile...

...Pang-jo Chun, PhD; Keiji Tsukada, PhD; Masahiro Kusumoto, MSc; Kazuaki Okubo, PhD This paper reports on a forensic investigation following the collapse of the Iwama Ohashi Bridge over the Shimanto River in Japan. The central section of the bridge failed in 2017 when a steel pier buckled...

...Richard Mathews, MA, CEng, FICE; Martin Hardman, BEng, CEng, MICE, MIStructE The December 2015 floods in Cumbria, north-west England, UK, were preceded by 3 weeks of extremely wet weather, which prompted the highway bridge management team of Cumbria County Council to review their response...

... of a structure detail is calculated for different monitoring options to determine the optimum duration for short-term monitoring campaigns. The proposed approach is illustrated by considering the field data from the Great Belt Bridge (Denmark). Motivated by the above, the authors discuss how much data in terms...
