Research

Focus areas

We conduct integrated experimental and numerical research toward low-damage high-performance earthquake-resilient building systems. We aim to reduce the sensitivity of the buildings' seismic response to the variability of the characteristics of the earthquake ground motions.

We look forward to working with industry partners to enhance the two way transfer of knowledge between practice and research.
