Research Experience

Photos from seismic experiments Dr. Panagiotou has led as Principal Investigator (a), co-Principal-Investigator (b, c) or PhD student researcher (d). (a) Shake-table test including physical modeling of the soil of rocking shallow foundations; (b) Full-scale test of a 1.2-m-deep RC beam for special moment frames; (c) shake-table test of earthquake-resilient rocking bridge column; (d) shake-table test of a full-scale 7-story RC wall building slice.

Dr. Marios Panagiotou during his five years of his PhD research studies as well as during his seven years as assistant professor at UC Berkeley has conducted analytical, computational and large-scale experimental research on earthquake structural engineering of RC structures and on the development of earthquake resilient tall buildings and bridges. During his career at UCB graduated five PhD students and was the principal or co-principal investigator of nine research grants with a total award amount of more than $ 1.5 Million. As part of these research projects he conducted some of the largest seismic experiments that have been conducted worldwide. 

 

As a PhD researcher, he was responsible for the seismic design, analysis, and shake-table testing of a full-scale 7-story building slice at the NEES@UCSD equipment site; this is the tallest structure ever tested on a shake table in U.S. In 2012, he received the ASCE Alfred Noble prize for his journal paper related to the 7-story building slice project.
