New Approach on the Safety Factor of Cable in Long-span Bridges

Abstract

<p>Super long-span bridge R&amp;D centre in Korea has investigated and developed the design guideline for cable supported bridges in accordance with Limit State Design concepts. Recently suspension and cable stayed bridges have become longer in span and huge tonnages of steel are required for cables. A significant part of the force in the cables of long span cable supported bridges arises from dead load. It is therefore obvious that significant cost savings can be obtained in cables and cable anchorages together with related savings in pylons and construction time by adopting the reasonable safety of cables.</p>
