General Description of the Research Project

Develop techniques for seismic evaluation and retrofit of buildings, and propose efficient methods of upgrading their structural integrity.
Although Bangladesh is located in a seismically active region, its capital city Dhaka is one of the world's most vulnerable urban centers due to its unordered and dense urban layout and low-quality building structures. In addition, building design and construction practices as well as structural characteristics differ significantly from those in Japan. To improve Dhaka's earthquake resilience, we aim to develop seismic evaluation and retrofit techniques suitable for buildings in Bangladesh, and jointly develop urban planning upgrading scenarios for efficiently deploying them on a societal level.

Realization of a safe and secure Dhaka through development of earthquake resilience technology
By upgrading Dhaka's building performance and urban center's resilience against earthquake damage, we aim to develop a safe and secure city and civil infrastructures for stable economic activity. As the techniques developed through this project address urban and building-related issues that are also commonly found in other developing countries, their worldwide dissemination has the potential to contribute to the safer global society.
