Cable Supported Footbridge Analysis with Construction Staging

A new trend in the design of footbridges in Turkey is to utilize cables. Some of these bridges have fake cables while others partially rely on a real cable system. These steel composite bridges, typically constructed over highways, span about 40-60 m. It was observed that bridges with fake cables can be substantially heavier than those with functional cables. This paper aims to study the importance of tensioning sequence of cables and the impact of construction staging on the design forces at the superstructure to have economical designs. A case study is illustrated as an example design.
