Engineering innovative seismic retrofits that don't break the bank

The video showcases a shake test conducted at Georgia Tech's structures lab to study how older reinforced concrete buildings respond to earthquakes. The research, supported by the National Science Foundation, aims to document building behavior and explore retrofit methods to enhance safety. The team built a test structure divided into sections for various retrofits, using materials like mortar, steel rods, and carbon fiber. The goal is to find less disruptive, economical retrofitting solutions that improve building performance during earthquakes. The research could significantly enhance the safety of older buildings in earthquake-prone areas.

What is the primary focus of the shake test conducted at Georgia Tech's structures lab?

• Testing the durability of skyscrapers

• Assessing the impact of hurricanes on buildings

• Studying the effects of wind on tall structures

• Evaluating the performance of two to five-story buildings

What is the main objective of the project supported by the National Science Foundation?
