STRUCTURAL ASPECTS OF CABLE-STAYED BRIDGE DESIGN

damping of a full-scale cable with a pair of passive–on magnetorheological (mr) dampers was tested. a cable of 215.58m long with the first mode frequency of 0.658hz was tensioned horizontally in cable prefabrication factory. two mr dampers were attached to the cable in an angle in the plane perpendicularly to the cable axis in 5m length from the cable anchorage. the applied voltage level was 0v...

This document describes an optimization problem of cable cross section of a cable stayed bridge considering constraints of cable stress and deck displacement. Since the bridge is still in study phase, the geometry and the mechanical characteristics are subjected to changes. In order to avoid creating different structural models, a program was produced to construct a model from geometrical and m...

Due to the influence of load, fatigue, corrosion, natural material aging and other long-term adverse factors, the state of the internal force of a cable-stayed bridge will be changed. These long-term effects can result in the bridge not meeting specified functional requirements, and potentially resulting in structural failure. This investigation focuses on the parameter identification of a gird...

The development of structural health monitoring (SHM) technology has evolved for over fifteen years in Hong Kong since the implementation of the “Wind And Structural Health Monitoring System (WASHMS)” on the suspension Tsing Ma Bridge in 1997. Five cable-supported bridges in Hong Kong, namely the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge, the Ting Kau (cable-stayed) B...

This article is concerned with the static analysis of structural cables used in railway overheads. Structural analysis computer program named ANSYS is used for analysis. Two effects are considered in the analysis. First one is the bending behavior effect of cables. BEAM188 in addition to LINK10 and LINK180 is used to see the difference in case of additional bending effect. Besides, LINK10 and L...

Extradosed bridges are similar to cable-stayed bridges in that stay cables are used for strengthening. Mter introducing the concept of extradosed bridges by J. Mathivat, this new type of bridges have been constructed in Japan. This paper shows some examples and the difference between extradosed and cable-stayed bridges in a structural aspect.

This paper develops and estimates a dynamic model of consumer behavior with switching costs in the market for paid television services. It is hypothesized that consumer choices of cable versus satellite providers are affected by the presence of switching costs, which in turn justifies forward-looking consumer behavior. The model allows for persistently heterogeneous consumer preferences. I esti...

The intention of the paper is to illustrate the ability of the probabilistic time-dependent reliability assessment procedure applied to non-linear suspended cable structure with rheological properties, when a rope made from the high strength synthetic fibres is used in order to demonstrate the new qualitatively different concept. Attention is turned to the individual main steps in the assessmen...
