About Speaker:

Dr. Shiling Pei is an Associate Professor at Civil and Environmental Engineering at Colorado School of Mines. He got his Ph.D. degree from Colorado State University in 2007. After that, he worked as an Assistant Professor at South Dakota State University from 2010 to 2013 before moving to Mines. His research focused on traditional and innovative timber systems, multi-hazard mitigation through performance based engineering, numerical modeling of structural dynamic behavior, and large-scale dynamic testing. Dr. Pei currently serves as the Chair of the ASCE Wood Technical Administrative Committee overseeing four wood engineering related committees. He is also Associate Editor of ASCE Journal of Structural Engineering. Dr. Pei is the member of the damage assessment team for the 2018 Hurricane Irma, focusing on residential building performances at Florida Keys. He is currently leading an NSF funded six-university collaboration effort to develop seismic design methodology for resilient tall mass timber buildings. This project involves multiple shake table tests, including the one that will be presented in this lecture and a 10-story full-scale tall wood building at NHERI@UCSD outdoor shake table planned in 2020. Dr. Pei is a registered Professional Engineer in State of California.


In July 2017, a full-scale two-story mass timber building was tested at the world’s largest outdoor shake table in San Diego, California. The test program is part of the NHERI TallWood Project funded by the National Science Foundation to develop and validate seismic design methodology for resilient tall wood buildings, namely multi-story mass timber buildings that will sustain only minor damage during large earthquakes. The entire test program consisted of three phases with different cross laminated timber lateral system solutions. This presentation will focus on the results from the first phase of this study, namely a post-tensioned rocking wall system. The building was subjected to a series of 14 earthquake excitations ranging from frequent earthquake events to maximum considered earthquake events. The test result showed that the structural system was essentially damage-free after these consecutive seismic loading events. The test proved that true seismic resilience can be achieved in mass timber structural systems using post-tensioned rocking CLT walls and glulam beam and column gravity frames. Some results from other phases of the tests will also be shared.
