STRUCTURAL ASPECTS OF CABLE-STAYED BRIDGE DESIGN

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...

Introduction Cable stayed bridges are a feasible choice for middle length spans and can be also an alternative to suspension bridges in the range of 1000 m spans. In the last three years, cable stayed bridges having more than 1 km span have been built in China (Sutong Bridge, 1088 m and Stonecutters Bridge, 1018 km). The increasing in length implies higher aeroelastic interaction with wind acti...

In this paper, a three dimensional analysis is performed to investigate the static instability of long-span cable-stayed bridges due to wind loading. Cables made of carbon fiber composite cable (CFCC) are studied. Nonlinearity due to displacement-dependent wind loading is considered. A 1400meter cable-stayed bridge model is used to investigate the static behavior of bridges with both steel and ...

On the basis of original design Ruck Bridge by Mr. Lin Tongyan, this paper modifies single-amplitude curved cable-stayed bridge to be an elliptical ring main beam two-amplitude deck, with a duck-egg-shaped arch tower and spatial cable net four planes, form four-cable-plane two-amplitude-curve for canyon-river topography, so as improve structural stress performance curved-beam bridge, promote tr...

There are multiple configurations permitted for a cable stayed bridge such as the number of spans, tower shapes, and cable arrangements. Therefore it is always important to study the behaviour of these types of structures against strong winds so that aeroelastic instabilities do not appear. This paper contains detailed aeroelastic analyses of three cable stayed bridges of very different configu...
