Special Issue Information

Dear Colleagues,

With the continuous expansion of transportation networks and the construction of increasingly long-span and complex bridge systems, ensuring structural safety and serviceability has become a critical priority. Modern bridge engineering must address not only challenging design and construction demands but also the long-term performance and resilience of bridges under various loading and environmental influences.

Advancements in structural health monitoring, artificial intelligence, and data-driven engineering have opened new avenues for improving the safety, durability, and maintenance efficiency of bridge infrastructure. These technologies enable real-time evaluation, early damage detection, and intelligent decision-making, greatly reducing the risk of unexpected failures and ensuring sustainable operation throughout a bridge’s lifecycle.

This Special Issue aims to gather innovative research, recent achievements, and engineering applications related to structural systems, monitoring technologies, and artificial intelligence in bridge engineering. Submissions should highlight methods and solutions that improve reliability, cost-effectiveness, resilience, and digitalization in the design, assessment, and management of bridge structures.

Potential topics include, but are not limited to, the following:

  • Large-span structures: Structural performance, design optimization, aerodynamic behavior, and dynamic performance.
  • Novel bridge design and construction technologies: Advanced materials, prefabrication, and adaptive structural systems.
  • Structural health monitoring in bridge engineering: Innovative sensing techniques, smart inspection systems, and real-time condition evaluation.
  • Load actions in bridges: Traffic loads, environmental loads, fatigue and creep effects, and loading mechanisms in complex operational scenarios.
  • Machine learning and deep learning in bridge engineering: Data-driven damage detection, pattern recognition, predictive analytics, and digital twin development.
  • Bridge disaster prevention and resilience: Monitoring and mitigation strategies for seismic events, extreme weather, impacts, and other hazards.

Field applications and engineering case studies: Practical demonstration of techniques across different bridge types and operating conditions.

This paper investigates lightweight structural systems based on pultruded GFRP girders for the replacement of deteriorated concrete bridge decks on existing piers and abutments. The study is motivated by the need to rehabilitate short- and medium-span bridges affected by aging deterioration such as reinforcement corrosion. The approach preserves existing piers and foundations and, when required, enables rapid deployment for temporary or emergency applications. The proposed GFRP deck–girder solutions significantly reduce structural mass compared to conventional concrete systems. This reduction leads to lower seismic demand and smaller horizontal forces transmitted to the substructures. The research assesses the structural performance and feasibility of these systems, with particular attention to strength and serviceability behavior. The objective is to identify solutions that can be replicated across different bridge configurations, while also outlining efficient strategies for onsite assembly. After a reasoned review of the solutions available in the literature and of the limitations related to deformability, strength, and instability for a preliminary analytical design approach, three-dimensional numerical simulations of GFRP bridge deck systems are performed to evaluate global behavior and load-transfer mechanisms. The latest design codes and guidelines for GFRP bridges are reviewed and applied. Based on the results, recommendations are provided regarding cross-sectional proportions and member slenderness. The numerical results are compared with the analytical design approach, showing that, under characteristic load combinations, maximum deflections can be limited to approximately L/300–L/400 when the beam depth-to-span ratio range is between 1/10 and 1/6. Within these relationships, spans between 10 m and 25 m are found to be efficient. Additional guidance is proposed for modular construction strategies based on standardized pultruded elements and factory-controlled bonded connections. Full article

Slender, lightweight and modern footbridges are particularly susceptible to vibrations induced by pedestrian activity. While extensive research has focused on vertical and lateral forces produced by walking, torsional moments generated by eccentrically walking pedestrians remain largely overlooked. Traditional assessments typically neglect these torsional effects, which can be critical when eccentric pedestrian loading excites torsional modes, especially in footbridges with asymmetric geometries. To address this, the paper considers the coupling between bending and torsional effects in both the pedestrian action and structure reaction, including pedestrian forces and moments, as well as bending-induced deflections and torsion-induced rotations of the cross-sections. A simplified method is also presented, allowing standard bending-only analyses to be easily adapted to include torsional effects using analytically derived correction factors. For validation, several experimental tests are conducted on an asymmetric curved footbridge located in Modena, Italy, characterised by coupled bending-torsional vertical modes and hosting different pedestrian densities, pacing frequencies, and crowd distributions (both uniform and eccentric). Experimental and numerical analyses demonstrate that neglecting torsional effects oversimplifies the assessment, highlighting the importance of accounting for bending-torsion coupling for the serviceability of asymmetric footbridges under eccentric near-resonance loading.
