Building ‘Belt’ Repairs Earthquake Damage

A ‘belt’ technology offers cheap and quick repair of earthquake-damaged buildings.

Metal straps are wrapped around each floor of the building, and the straps are then tensioned either by hand or using compressed air tools. The technology is designed for use on reinforced concrete frame buildings – a common construction technique used around the world, including countries like Haiti. Unlike other repair methods, it does not require expensive materials or a high level of technical knowledge.

“The strapping works very much like a weight-lifter’s belt, by keeping everything tightly compressed to reduce tension on the concrete columns of the structure," said lead researcher, Professor Kypros Pilakoutas.
