Vision, Tasks, and Results.

Project Overview

With global urbanization trends, the demands for tall residential and mixed-use buildings in the range of 8~20 stories are increasing. One new structural system in this height range are tall wood buildings which have been built in select locations around the world using a relatively new heavy timber structural material known as cross laminated timber (CLT). The Vision of this project is to develop and validate a seismic design methodology for tall wood buildings that incorporates high-performance structural and nonstructural systems and can quantitatively account for building resilience. This design methodology will be validated through a series of full-scale shaking table tests of a 10-story CLT building specimen at the world's largest outdoor shake table at NHERI@UCSD.

This project builds on existing research and engineering knowledge on mass-timber construction and performance-based design. The scope of this project is summarized in the following figure:
