Shake table test on transverse steel damper seismic system for long span cable-stayed bridges
Engineering structures, 2019In current transverse seismic design of long span cable-stayed bridges, the conventional transverse fixed system (TFS) is usually adopted. This strategy inevitably increases seismic demands of substructures and towers, leading to high seismic-induced ...

Seismic response of a long span cable
Earthquake Engineering & Structural Dynamics, 1991AbstractThe dynamic response of a single span cable due to a travelling seismic excitation is studied in this paper. The influence of propagation time between the supports is investigated in detail. The importance of considering both vertical and longitudinal equations of motion in the analysis is highlighted.

Long‐term characteristics of XLPE cables
Electrical Engineering in Japan, 1993AbstractTo study the long‐term characteristics of XLPE cables installed in free air and in water, aging tests were conducted under various testing conditions using XLPE cables with both 3.5 mm and 6 mm insulation.From the Weibull plots of lifetime distribution under the voltage stress EL as the minimum breakdown strength, the minimum value of time to ...

Advances in Structural Engineering, 2019
Bridges are inevitably affected by daily, seasonal and annual air temperature and solar radiation. The thermal effects on bridges, especially for long-span cable-stayed bridges with composite girders, are significant and complicated.

Long Distance Telephone Circuits in Cable*
Bell System Technical Journal, 1932This paper first very briefly reviews the history of long distance telephone cables in the United States. A statement is then given of the basis of the electrical design of present day cables, followed by a discussion of the standards applied to cable circuits and the application of cables to the telephone needs of the country. While the present system

How Cables Fail-the Myths and Fundamentals to Ensuring Long Cable Life
2018 IEEE Electrical Insulation Conference (EIC), 2018“How do cables fail?” is a loaded question. The mechanisms by which many cables fail are presumed unknown due to the catastrophic failure site being un-diagnosable post failure. There are many myths regarding the phenomena of what causes a cable to fail. The expected life of cables is also a hotly debated topic.

Beachpull Installation of Long Pipelines and Cables
Volume 3: Pipeline and Riser Technology, 2012Conventional pipelay (i.e. S-lay) is not feasible in shallow water locations owing to the draft of pipelay barges. Pipelay using beachpull method provides an alternative to such restrictions. A typical long beachpull operation in shallow water environment presents a substantial challenge, which calls for a thorough engineering analysis along with a ...

Damping properties of FRP cables for long-span cable-stayed bridges
Materials and Structures, 2015In this study, the damping properties of carbon fiber reinforced polymer (CFRP) and basalt fiber reinforced polymer (BFRP) cable potentially applied in long-span cable-stayed bridges were simulated and evaluated based on experimental data and theoretical derivations.
