Experimental Study on Vortex-Induced Vibration of Riser under Wake Interference

Shiyou jixie, 2022
To explore the relationship between the incoming flow velocity and the response characteristics of risers under different arrangement modes,and to compare and analyze the flow interference effects under different working conditions,the vortex-induced ...

Resistance of Trapezoidal Sheeting in Fire

ce/papers, Volume 8, Issue 6, Page 682-686, December 2025.
Abstract Cold‐formed steel trapezoidal sheeting has a significant decrease of its bending resistance in fire due to the small sheet thickness. The bending resistance is generally reached within 10 minutes of a fire. However, the failure in bending is followed by transitions from bending behaviour to a catenary action.

Testing and modeling dowel and catenary action in rebars crossing shear joints in RC [PDF]

Engineering Structures, 2017
Abstract This paper presents a detailed study of the shear behavior of two-sided dowel joints, which includes initiation of dowel action at small shear displacements and development of full catenary action in the reinforcement at large displacements. In addition to experimental results, the paper also presents a simple, second order plasticity model ...

Tracking Mooring Lines of Floating Structures by an Autonomous Underwater Vehicle

Journal of Field Robotics, Volume 42, Issue 8, Page 4589-4608, December 2025.
ABSTRACT This study presents a novel method for tracking mooring lines of Floating Offshore Wind Turbines (FOWTs) using an Autonomous Underwater Vehicle (AUV) equipped with a tilt‐controlled Multibeam Imaging Sonar (MBS). The proposed approach enables the AUV to estimate the 3D positions of mooring lines and safely track them in real‐time, overcoming ...

Finite Element Modelling of Catenary Action in a Cross-Laminated Timber Floor System

, 2021
Buildings taller than four storeys require the designer to mitigate consequences of unexpected events, e.g. terrorism or accidents, such that a disproportionate collapse can be avoided after initial damage. One approach to halt damage propagation is using structural robustness, i.e. by providing alternative load paths. For platform-type cross-laminated

$G$-prime and $G$-primary $G$-ideals on $G$-schemes

, 2014
Let $G$ be a flat finite-type group scheme over a scheme $S$, and $X$ a noetherian $S$-scheme on which $G$-acts. We define and study $G$-prime and $G$-primary $G$-ideals on $X$ and study their basic properties.

Evaluating Different Approaches for Modelling Rotor Aero‐Servo‐Dynamics in Frequency‐Domain Analysis of Floating Wind Turbines

Wind Energy, Volume 28, Issue 11, November 2025.
ABSTRACT Computationally efficient frequency‐domain models can play a very important role in facilitating conceptual design optimization of floating wind turbines (FWTs). However, achieving sufficient accuracy in such models is challenging due to the nonlinear variation of the aerodynamic loads, particularly the interaction between the floating ...

Study on the Component-Based Model of an All-Welded Beam-Column Connection for Progressive Collapse Analysis

Advances in Civil Engineering, 2020
The mechanical behavior of all-welded beam-column connections of steel frames during progressive collapse was numerically studied using finite element simulations. The validation of the numerical model was based on a previous test model.

Observations of Subduction, Downward Heat Flux and Dense Filament Collapse in the Northern Gulf of Mexico

Journal of Geophysical Research: Oceans, Volume 130, Issue 11, November 2025.
Abstract Submesoscale processes are important contributors to the global heat budget and generally support upward heat transport through restratification. However, in salinity‐stratified regions, such as the northern Gulf of Mexico with its influx of freshwater from the Mississippi‐Atchafalaya river system, temperature can act like a passive tracer and
