The lab studies how to make concrete bridges and roads more resistant to earthquakes and tsunamis.
AboutAbout the lab
Ensuring the safety and security of infrastructure.
The Akiyama Lab conducts research to improve the safety of infrastructure structures, such as concrete bridges.
The lab studies methods to make structures, as well as road and railway networks, less prone to failure and longer-lasting even when multiple factors such as earthquakes, tsunamis, and corrosion (multi-hazard) occur together.
Using both experimental and analytical approaches, the lab aims to realize safe and secure infrastructure.
Key terms
- Multi-hazard
- Multiple disasters, such as earthquakes, tsunamis, and heavy rain, occurring in combination
- Precast construction
- A construction method in which components are made in advance in a factory and assembled on site
- Decarbonized concrete
- A new type of concrete that reduces CO2 emissions or captures and fixes CO2

ResearchResearch themes
The lab studies how to improve the safety of infrastructure structures such as concrete bridges, and of the road and railway networks that include them. Against multiple hazards such as earthquakes, tsunamis, and corrosion, it investigates methods to enhance structural safety and extend service life, through both experiments and analysis.
*Illustrative imageRisk assessment of Nankai Trough earthquakes and tsunamis
The lab develops analysis techniques that quantify damage to road structures and the impact on network recovery under multi-hazard scenarios, in which multiple disasters such as an earthquake and a tsunami occur together.
*Illustrative imageDamage-free structures and precast bridges
The lab is developing bridge structures that resist damage even under strong shaking, so that emergency vehicles can pass after an earthquake, as well as precast structures that can be used as emergency bridges.
*Illustrative imageClimate change and infrastructure design
The lab evaluates the effects of climate change, such as sea level rise and more intense heavy rainfall, on infrastructure structures, and studies design methods for structures that take these effects into account.
*Illustrative imageDevelopment of decarbonized concrete
The lab is developing WMaCS, a new concrete material made from seawater and CO2 that fixes CO2 as carbonates, with the aim of using it as a construction material.
