“…This pattern demonstrates that an escalation in the number of keys within the segmental U-shaped bridge contributes beneficially to the contraction of the tensile zone. The present inquiry delves into the shear capacity of segmental U-shaped bridge joints by applying the shear capacity formula endorsed by the American Association of State Highway and Transportation Officials (AASHTO) [29]. The shear capacity is computed as per the following equation:…”

This paper presents an in-depth analysis of the mechanical behavior and joint shear capacity optimization of segmental U-shaped bridges, with a focus on the application of precast segmental techniques in the construction of U-beam bridges widely used in urban rail transit networks. This study further explores the roles of key position distribution and size in the overall stability and service behavior of such structures. Considering the critical case study of the Colombia Bogotá Metro Line 1 project, finite element modeling was carried out using ABAQUS 6.14 to simulate concrete material behaviors and to evaluate the stress–strain relationship in accordance with the concrete plastic damage model and existing standards. This research identifies the significant contribution of keys in minimizing deformation and enhancing shear capacity, demonstrating the pivotal influence of shear key design on the mechanical behavior of segmental bridges. By calculating the shear capacity under different cases, this study provides recommendations on key distributions and dimensions that optimize joint shear capacities, indicating that augmenting key size within the web plate section decisively reinforces the bridge’s mechanical resilience.

<p>Modularity plays a key role in the rationalisation of industrially produced consumer goods and the optimisation of their fabrication technologies. With reduced numbers of individual components, rationalisation, automation, and digitalisation of involved processes become more feasible, and reduction of material quantities and process waste can be achieved. The user further benefits from the possibility of replacement and repair of damaged components as well as disassembly and reuse of components at the end of life. To transfer these benefits to loadbearing engineering structures, the authors propose a modular product family for footbridges using precast segmental technology with dry joints and external CFRP post-tensioning. This article describes the applied principles and benefits of modularity, the modular footbridge design and the influence of dry joints and external CFRP post-tensioning on the bridge’s overall structural performance.</p>
