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 mass timber buildings. The Vision of this project is to develop and validate a seismic design methodology for tall wood buildings that 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:
