“…For instance, the cause of the collapse of the Chirajara Bridge, which was a cable-stayed bridge still under construction, was attributed to a weakness in the tower's strength caused by a flawed design [39]. Lessons learned from incidents such as the collapse of the FIU pedestrian bridge in Miami, FL, USA [40] and the collapse of the Butou Bridge in Guangxi, China, due to excessively high abutments underscore the importance of prompt implementation of countermeasures when design errors lead to malfunctions.…”

The construction of sustainable bridge projects has become a global mission and challenge in the 21st century. Unfortunately, there has been a rise in bridge collapse incidents due to various factors in recent years both during the construction and service phases. These incidents have resulted in significant loss of life and property damage, exacerbating the five sustainable development issues faced by bridge engineering: natural, resource, environmental, social, and economic factors. As a result, the prevention and resolution of bridge collapse accidents have garnered attention from professionals, research institutions, and government departments, making it a prominent research area. In line with the sustainable development concept of bridge engineering, this article classifies the causes of bridge collapses into two categories: those occurring during the construction phase and those happening during the service phase; the latter includes lack of inspection, maintenance and management, external natural factors, and human factors. Furthermore, this article thoroughly examines the existing national management framework, identifying the dilemmas that hinder its effectiveness in regulating bridge collapse prevention. Finally, several effective suggestions are proposed for the prevention of bridge collapse incidents. These recommendations aim to motivate governments, project owners, designers, constructors, managers, and users to actively develop and promote high-quality sustainable bridges.

“… 1 . Due to the above problems, many bridges around the world collapsed, such as the Ezhou huhua Interchange Ramp 2 , Morandi Bridge in Italy 3 and Florida International University pedestrian bridge 4 , etc. Those collapses of bridges caused serious disastrous disasters to people's lives and the social economy, which prompted people to hope for a system with a comprehensive and long-lasting health monitoring on the bridge.…”

Since the damage of the bridge structure may cause great disasters, it is necessary to monitor its health status, especially the bridge bearing, the important connecting component of the bridge's upper and lower structures. Nowadays, manual inspection is the main method to get the information of the bridge bearings’ work status. However, occasional damage of bridge bearing may not be detected in time, and sometime the installation position of the bearing makes the manual inspection on bridge bearing difficult and even impossible. Therefore, in order to know the work status of the bridge bearings timely, an intelligent remote monitoring system for the bridge bearing is developed. A 32-channel real-time acquisition system is designed by using an AD7768-1 analog-to-digital converter and Xilinx Spartan-6 Field Programmable Gate Array for interface stress continuously acquired in the bridge bearing. To assure the good linearity and low noise performance of the monitoring system, the data acquisition card is meticulously designed to reduce noise from both hardware and software and realize high-precision acquisition. Through the establishment of the monitoring server, the compressive stress data can be displayed synchronously and the overpressure situation can be alarmed in real-time. The experimental results show that the accuracy of the calibrated sensor is within 1.6%, and the detection error of the acquisition board is less than 200 μV. The acquisition system is deemed to have considerable advantages in accuracy and applicability.

“…Several bridge failures that occurred in the last half-century were due to underestimated design forces, as noted in the collapse of the Florida International University pedestrian bridge. Zhou et al [10] outlined that the main cause of this collapse was the re-tensioning operation on prestressing rods per the bridge design plans, which produced additional loading on the diagonal members and thus shear failure. This study demonstrated the importance of timely accounting for countermeasures in case of malfunctioning, even during the construction stage.…”

Building Information Modelling is receiving increasing attention as an emerging technology for enhancing the life‐cycle performance of facilities. The cooperation between all professionals involved in the construction chain allows to reproduce digital twins of the structures including information related to different disciplines, such as structural and architectural aspects. In this context, the use of Building Information Modelling, combined with an automatic tool to predict risk indices, could be particularly useful when dealing with existing bridges due to the significant structural deficiencies recently demonstrated by numerous bridge collapses worldwide. This paper explores the development of a BIM‐based procedure to bring greater value in the design, construction, maintenance, and inspection stages. The procedure is applied to existing bridges and it allows to estimate a structural risk prioritization class of bridges according to maintained activities, periodical inspections, structural detailing and modelling uncertainties. The automatic BIM‐based tool uses a workflow developed in Dynamo, and is able to automatically update the structural risk class and to provide warning if the structural safety index exceed defined thresholds.
