Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Influence of mix design method on the shear capacity of reinforced concrete beams made with high‐quality recycled coarse aggregate

Structural Concrete, EarlyView.
Abstract This study investigates the shear capacity behavior of reinforced concrete (RC) beams without stirrups incorporating recycled coarse aggregate (RCA). An extensive database comprising 269 experimental data points from 40 journal articles published between 2001 and 2025 was compiled, excluding specimens with recycled fine aggregate or fiber ...

Ungulate substrate use in fauna passages

Wildlife Biology, EarlyView.
Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Towards High Circularity: Reconfiguring Firm‐level Strategy

British Journal of Management, EarlyView.
Abstract The transition to a circular economy (CE) is increasingly recognized as a strategic priority for companies striving for more sustainable business operations. Previous CE research adopted different firm‐level strategy perspectives with varying degrees of alignment to the management literature.

THE ANALOG CITY: Maintaining Everyday Life Through Repair and Jugaad

International Journal of Urban and Regional Research, EarlyView.
Abstract Urban scholarship consistently discusses improvisation and heterogeneity as central to urban life in the global South. In this article, I bring together scholarship on urban improvisation and the digital world of smart cities to understand the city as analog.
