The 1915 Çanakkale Bridge spans the Dardanelles at the western end of the Sea of Marmara. Part of the Kınalı-Balıkesir Motorway in the northwest of Turkey, it is the longest suspension bridge in the world. The 2023 m long main span leaves a 1600 m x 70 m navigation channel. Two 318 m steel towers support the main suspension cables at 38 m separation. The deck comprises a pair of 14.5 m wide, 3.5 m deep aerofoil steel box girders connected at intervals by transverse box girders. Eight 450 t capacity lifting gantries were required for deck erection, two for each side span and four for the main span. There were 153 deck segments to be erected, of which 143 were erected with the gantries. The gantries were self-erected onto the main cables. Environmental conditions and maritime traffic in the strait were key factors in the development and choice of construction methods for the bridge. This paper describes deck erection with the lifting gantries and focuses on the development, design, testing and operation of the self-erection system; an innovative solution which maximises pre-assembly off the critical path, minimises disruption to shipping and allows installation of the gantries without floating cranes.

This paper benchmarks the challenges involved with major sea, or fixed link, bridge crossings from their planning to final construction. Initially it gives an overview of existing major fixed link crossings globally, including statistical information such as length and inflation adjusted project costs. Well known links such as the Oresund crossing and the more recent Hong Kong Zhuhai Macau crossing have been included in the data. The paper considers the construction methods required to surmount the challenges of bridging such crossings, and how advancements are making long mooted crossings more feasible. The paper presents statistics on the construction time period for these crossings and considers links between construction time, cost aspects, and carbon emissions of such crossings. Finally, the paper looks to the future: How the data can be used to better bound estimates of time, costs, and emissions for fixed link projects. The paper also studies some of the more notable future fixed link projects and their viability.

In a complex network such as a road infrastructure system, disruptive events have direct consequences (loss of lives, structural damage, economy losses etc.) related to the sub-system level directly affected, as well as indirect consequences on the overall system level such as loss of functionality and related monetary consequences. To quantify the influence of component failures on the network performance, complex network analysis allows representing the relation among its components and the consequences in order to estimate the functionality of the system. The serviceability of a road network is the possibility to use it during a given time period as representing the performance of the system. Thus, the time to restored serviceability after a disruptive event is measuring road transportation resilience. In this paper, network analysis with the help of OSMnx Python package, supplied by road network data from OpenStreetMap, is applied to a Spanish motorway case study. Loss of serviceability index is obtained combining the results of road links failure scenarios based on shortest paths and travel times in order to estimate road network resilience. The proposed methodology allows a suitable evaluation of the influence of road links in the risk assessment and management strategies by road infrastructure owners and managers.

The Jinhai main bridge is designed as a cable-stayed bridge with a single deck carrying a double rail track in the middle and 3 lanes of highway on each side. The structural design combines a rigid frame with continuous spans, effectively improving the overall structural rigidity to meet the requirements for railway traffic, and meanwhile minimizing the temperature effects from a long continuous structure. The deck girder adopts a steel box with large cantilever flanges, which is cost-effective. The steel pylons are designed with four legs which locate on top of the deck instead of on pile cap, to minimize the size of the pile foundation. To improve the construction efficiency, the main girder and pylons are pre-fabricated into large-scale components and erected using heavy equipment.

The A554 Tower Road connects Wallasey and Birkenhead on the Wirral, North West England. The road crosses the entrance to Birkenhead Docks from the River Mersey via a moveable bridge which is of major strategic importance in the local highway network. The previous “A” bridge, built in 1933, was a Scherzer type bascule lifting bridge with 34.4m main span, one of four similar bridges that once existed along Tower Road. The deteriorating condition of the bridge, the increasing maintenance costs and the consequential impact of maintenance on the local economy resulted in a decision to replace the bridge with a modern, low maintenance lifting bridge. This paper provides the background to the bridge replacement project, including the reasons for replacement with a similar Scherzer bascule bridge. The civil, mechanical and electrical design is described and some of the significant issues encountered during implementation and commissioning are discussed. The new bridge has successfully created a local landmark, contributing to the client Wirral Council's vision for the redevelopment of this dockland area as part of the Wirral Waters Regeneration project.

Multi-span bridges having bi-directional ductile diaphragm consisting of Buckling Restrained Braces (BRBs) can provide resilient bridges with damage-free columns, at low cost, while minimizing displacements demands to levels that can be easily accommodated. Towards the goal of better understanding the behavior of this type of bridges and its advantages, a parametric analysis was performed with regular multi-span simply-supported bridges considering variations in pier stiffness, BRB target displacement, BRB yield displacement, and numbers of spans. Bridges were analyzed in the longitudinal direction. BRBs were designed using nonlinear response history analysis. The demands of the designed bridges were analyzed to understand the influence of the various parameters considered. It was observed that the proposed system is able to reduce the demands in piers such as to keep them elastic and limit the displacement demands in expansion joints (which makes it easier to prevent unseating in retrofit situations). It was also determined that, according to fatigue damage calculations, it is not necessary to replace BRBs after an earthquake.

Structural health management constitutes an essential factor in ensuring the durability of concrete structures. Cracks in concrete, reinforcement corrosion, alkali-silica reaction, and efflorescence attacks are commonly concrete defects that can be identified visually. However, detection and classification of these defects in concrete bridges and other high-rise concrete structures are difficult and expensive process in manual approaches. In this research, a deep learning application is applied to detect and classify concrete defects. Concrete images from the public repository were used to create the explored database. The database was divided into training and validation subsets. The visual geometry group (Vgg19), neural search architecture (nasnetlarge), and residual inception block (vinceptionresnetv2) algorithms were used in analysing the images. The results of the overall performance show that Vgg19 algorithm recorded higher accuracy in the detection and classification of concrete defects as compared to nasnetlarge and inceptionresnetv2 algorithms. The efficiency of the proposed approach was evaluated using a new dataset containing images of concrete defects. The outcome of this research strongly shows that deep learning models could enhance the efficiency of concrete structural health monitoring in a multi-classification scenario.

Chloride-induced corrosion is one of the most important reasons for the strength degradation of reinforced concrete (RC) bridges. As the piers of RC bridges are important element to sustain lateral loads, corrosion of columns in pier may lead to significant degradation. So it is necessary to have an appropriate evaluation technique to assess the effect of corrosion on the RC columns behaviour. Numerical modelling approaches which are based on the concentrated plastic hinge can predict structural behaviour rapidly and with acceptable accuracy which are highly regarded by engineers. In this study, a numerical approach is conducted to develop an empirical lumped plasticity model for corroded RC column elements. 13440 RC column specimens, including corroded and uncorroded, rectangular, and circular cross sections are analysed under monotonic and cyclic loading. Lumped plasticity model is extracted based on the regression of the cyclic and monotonic analysis results. Finally, calibrated model is verified through experimental and out-of-parametric study models with high accuracy. The new developed plastic hinge model can be used to model and analyse corroded bridge columns rapidly. The result can be appropriate to be employed for modelling in the further assessment such as fragility analysis or rehabilitation.
