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: In this paper, an innovative hamburger-shaped eddy current damper (HSECD) is presented to mitigate the responses of civil structures subjected to wind excitations. The damper’s capacity to dissipate energy is significantly ...

Abstract: Many transmission towers have collapsed during typhoon events, and the design wind loads in most current standards consider only the turbulence characteristics of monsoons. The gust response factor (GRF) is a parameter ...

Abstract: This paper estimates the wind-resistance of a lightning-damaged transmission tower. The buckling cause of a tower member under lightning excitation is reexamined through an overall tower model, and the modelling method of ...

Abstract: Insulator fatigue, lighting strike, or flashover could result in the breakage of insulator strings. Insulator breakage can cause conductor impingement on the ground, which is a threat to the safe operation of a transmission ...

Abstract: This study aims to explore the role of built environments affecting emergency medical services (EMS) responses to traffic crashes. Specifically, this study integrated socioeconomic databases with a crash database that ...

Abstract: Currently, the buffeting analysis for transmission lines (TLs) only involves the excitation of horizontal turbulence, while numerous investigations have proven that significant vertical turbulence exists in many wind fields. ...

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 ...
