Abstract: Because transmission tower-line systems are always exposed to the natural environment, such structures are vulnerable to various meteorological conditions, and the rupture of a transmission line is a particularly serious ...

Abstract: Given the premise that a communication tower is a vital infrastructure that may collapse when encountering a wind disaster, this paper focused on investigating the collapse mechanism and collapse fragility of a communication ...

Abstract: Shear stress transport (SST) k–ω model and detached eddy simulation (DES) have been widely applied in crosswind stability simulations for trains in the literature. In the previous research, the influence of the SST and DES ...

Abstract: Most current studies on the seismic responses of transmission towers are performed using two or three translational components of ground motion as earthquake inputs. In this study, a novel surface fitting method (SFM) for ...

Abstract: Unsaturated transport of water and chloride into concrete was investigated using capillary absorption tests and molecular dynamics (MD) modeling. Results showed that a linear relation between capillary absorption rate and ...

Abstract: Neither structural properties nor wind loads are deterministic; accordingly, a fragility analysis of overhead transmission towers can be employed to comprehensively evaluate their strength capacity. Here, a fragility ...

Abstract: This study aims to explore the effects of helmet structure designs and wearing modes on the protective performance of safety helmets under the impact of falling objects. Four helmet types (no helmet, V-shaped, dome-shaped, ...
