Effective Gap Size Index for Determination of Optimum Separation Distance Preventing Pounding between Buildings during Earthquakes

Applied Sciences, 2021
Seismic excitations may lead to collisions between adjacent civil engineering structures, causing major damage. In this paper, an effective equation for calculating the gap size index is proposed so as to provide the optimum separation distance ...

Seismic Pounding between Adjacent Building Structures

Electronic Journal of Structural Engineering, 2006
Investigations of past and recent earthquake damage have illustrated that the building structures are vulnerable to severe damage and/or collapse during moderate to strong ground motion.

Testing nest deterrents for Chihuahuan ravens on H‐frame transmission structures

Wildlife Society Bulletin, 2015
Chihuahuan ravens (Corvus cryptoleucus) regularly perch and nest on electric utility structures. Because ravens perch on overhead shield wires, for which no perch discourager exists, management focuses on nests.

Analysis of Pounding between Two Adjacent Buildings during an Earthquake [PDF]

Port Said Engineering Research Journal, 2019
The aim of this paper is to study the effect of collisions between the adjacent structures during the earthquake and its effect on the behavior of the structure. The collisions could lead to local damage or even total collapse of colliding structures.

Protecting Against Collateral Damage to Non-cardiac Structures During Endocardial Ablation for Persistent Atrial Fibrillation

Arrhythmia & Electrophysiology Review, 2022
Injury to structures adjacent to the heart, particularly oesophageal injury, accounts for a large proportion of fatal and life-altering complications of ablation for persistent AF. Avoiding these complications dictates many aspects of the way ablation is

Vibration Analysis and Models of Adjacent Structures Controlled by Magnetorheological Dampers

Shock and Vibration, 2017
This paper deals with the vibration analysis of adjacent structures controlled by a magnetorheological (MR) damper and with the discussion of a numerical procedure for identification and definition of a reliable finite element model.

Numerical Modelling of Structures Adjacent to Retaining Walls Subjected to Earthquake Loading

Geosciences, 2020
In an urban environment, it is often necessary to locate structures close to existing retaining walls due to congestion in space. When such structures are in seismically active zones, the dynamic loading attracted by the retaining wall can increase. In a
