Disintegration highway: Towards a psychogeography of planetary urban breakdown

open access: yesSingapore Journal of Tropical Geography, Volume 46, Issue 1, Page 138-156, January 2025.
This paper develops a psychogeographical approach to our apocalyptic urban present, based on a journey down a highway on the outskirts of the city of Iquitos in the Peruvian Amazon. The intensity of psychogeographical method brings out elements of the senselessness and violence of planetary urbanization imperceptible at more abstract levels of analysis,

Output Only Damage Detection of a Steel Truss Bridge Based on a Semisupervised BiLSTM Modeling Scheme

open access: yesStructural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
The application of machine learning techniques in bridge health monitoring is gaining widespread popularity as it overcomes the problems faced by conventional methods. However, the scarcity of labeled data for damaged bridges in training the model acts as a hindrance.

Influence of Bridge Bearings on Mitigating Nonlinear Seismic Responses of Straddle‐Type Monorail Trains

open access: yesStructural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Straddle‐type monorail systems (STMSs) are increasingly adopted as medium‐capacity transit solutions to alleviate urban traffic congestion. However, their operational resilience during earthquakes is challenged by the low lateral stiffness of track beams and single‐column piers, with critical components like bearings and piers vulnerable to ...

Assessment of multiaxially loaded safety components with uniaxial stress state in fatigue critical sites caused by design Beurteilung multiaxial belasteter Sicherheitsbauteile mit uniaxialem Spannungszustand verursacht durch Geometrie in kritischen Stellen

open access: yesMaterialwissenschaft und Werkstofftechnik, Volume 55, Issue 11, Page 1462-1483, November 2024.
The focus of this study, using results obtained with hollow specimens of the alloy Al 2024 T3 (AlCuMg2 T3) with a one‐sided bore, was to determine if, under multiaxial loading, the fatigue strength can simply be assessed without the application of any multiaxial strength hypothesis. This is the case because, despite the multiaxial loading, in the notch
