In modern building designs, fiber reinforced polymer (FRP) composite reinforcement is being used to strengthen buildings and towers to reach even taller heights. For example, composite retrofitting is being incorporated by more and more architects to protect them from earthquakes and to repair damaged architectural columns. Here is a sampling of the tallest buildings that have been built in the past two years and how they are using FRP to reach new heights.
The Tokyo Skytree was completed in May 2012. It is the second tallest structure in the world at 2,080 feet. Tokyo Skytree is a telecommunications tower and observation deck that is currently using reinforced concrete for seismic protection. This is especially important in earthquake- prone Tokyo.
The Makkah Royal Hotel Clock Tower
Makkah, Saudi Arabia
Also known as Abraj Al-Bait Towers, was completed in 2011 and opened in 2012. At 1,972 feet, it is the tallest clock tower and fourth largest structure in the world. The exterior structure includes over 40,000 square-meters of FRP panels and cladding. The clock hands are also composite laminated structures.
