Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Stochastic Improvement of Cyclic Railway Timetables [PDF]

Real-time railway operations are subject to stochastic disturbances. However, a railway timetable is a deterministic plan. Thus a timetable should be designed in such a way that it can cope with the stochastic disturbances as well as possible.

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

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

Structural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Towards Harmonized GHG Assessment Methods for Rail Infrastructure: Criteria for a Structured Method Development

Future Transportation
Greenhouse gas (GHG) emissions from rail infrastructure are increasingly examined in response to climate policy demands. Yet current assessment methods, such as ISO-based LCAs, FTIP, “Standardisierte Bewertung”, EN 15804 with c-PCR 023, and EIB’s Climate

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.

Behavior of turnout sleepers in a large-scale ballast box test

Scientific Reports
Turnouts are essential components of the railway infrastructure. Their sleepers change in length leading to asymmetric loading and structural discontinuities.

Effects of complex soundscapes on the occurrence of Anaxipha pallidula in isolated green spaces in Tokyo

Wildlife Biology, EarlyView.
Urban green spaces experience a mix of natural and anthropogenic noises, which could disrupt the vocal communication of several species. This study investigated how such complex soundscapes affect the occurrence of Anaxipha pallidula, which communicates through calls, focusing on both sound level and quality.

Graph neural network‐based attack prediction for communication‐based train control systems

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract The Advanced Persistent Threats (APTs) have emerged as one of the key security challenges to industrial control systems. APTs are complex multi‐step attacks, and they are naturally diverse and complex. Therefore, it is important to comprehend the behaviour of APT attackers and anticipate the upcoming attack actions.
