Abstract

Cable stayed bridges are critical components of our infrastructure and carry ever increasing traffic

flows connecting locations and people. These landmarks do not just have to be safe and function

reliably, but in the modern world of connected objects they can become a powerful tool to enhance

the public experience and even be used as a screen to display visual content. New solutions exist to

improve the resilience of stay cable bridges. An innovative solution to mitigate the risk of snow and

ice accretion on stay cables and a novel protection system withstanding severe fire loading from

hydrocarbon pool fires has been developed. In addition an integrated LED lighting system is

proposed to add new functionalities by embedding durable, waterproof, replaceable and low

maintenance LED modules into the HDPE stay pipe. The resulting array of LEDs can be used to display

varying visual content from simple color schemes to animated sequences.
