報告內容：Wood has thousands of years of history as a building material but has also been restricted by building codes and regulations following the industrial revolution. Wood building is viewed as a cost-effective, but less engineered system mainly for low-rise options. The building codes that govern wood construction is not as rigorous as that for steel and concrete. As the result, many existing wood buildings exhibit poor performance in case of natural hazards. And there are a lot of them. This situation presents a great challenge for civil and structural engineering as well as numerous opportunities. Mass timber construction is a relatively new way of utilizing wood material for modern, high performance buildings at both large and small scales. It gives rise to the currently trending conception of wooden sky-scrapers. This presentation will provide a brief history of wood utilization as a building material, discuss the pros and cons of wood structural systems based on finding of past research efforts, and introduce the current trend of building with mass timber, including an ongoing effort to design and test a 10-story full scale resilient wood building at NHERI@ UCSD.
報告人简介：Dr. Shiling Pei received his Ph.D. in Civil Engineering from Colorado State University in December 2007 and joined the faculty of Civil and Environmental Engineering at Colorado School of Mines in Fall 2013. Before that, he worked as an Assistant Professor at South Dakota State University from 2010 to 2013. His research focused on multi-hazard mitigation through performance based engineering, numerical modeling of structural dynamic behavior, traditional and innovative timber systems, and large-scale dynamic testing. Dr. Pei received the 2012 ASCE Raymond C. Reese Research Prize for his work on seismic performance of mid-rise wood frame building. He is the author of the Seismic Analysis Package for Woodframe Structures (SAPWood) as part of the NSF (NEESR) funded NEESWood project, and served as one of the lead researchers in shake table testing of a full-scale 7-story wood-steel hybrid building at Japan’s E-defense shake table. Dr. Pei is the member of the damage assessment team for the 2011 Tuscaloosa and Joplin tornados, focusing on residential building performances. He is currently leading an NSF funded six-university collaboration effort to develop seismic design methodology for resilient tall cross laminated timber (CLT) buildings. This project involves shake table testing of a 10-story full-scale tall wood building at NHERI@UCSD outdoor shake table planned in 2020. Dr. Pei currently serves as the Chair of the ASCE Wood Technical Administrative Committee overseeing four wood engineering related committees. Dr. Pei is a registered Professional Engineer in State of California.
