There are many aging bridges in service in the US and around the world that were not constructed to modern seismic design codes and standards. As a result, they are expected to perform poorly during intense earthquake ground shaking. Older reinforced concrete (RC) bridges, in particular, are often supported on...
The use of high strength steel reinforcement has the potential to provide economic and constructability benefits when used in reinforced concrete structures. However, more research is needed to justify and confidently allow its use. Current design provisions limit the nominal yield strength of reinforcing steel bars to 60 ksi (420...
Cross-Laminated Timber (CLT) is one of the latest engineered wood products to show promising structural features for a variety of structural purposes including resisting lateral loads. For CLT to be widely adopted, its modal behavior needs to be fully evaluated through experimental and numerical methods. It is important to the...
