World's Largest Earthquake Test
Pleasanton, Calif. : Colorado State University and Simpson Strong-Tie, along with other partners, successfully led the world's largest earthquake shake table test in Japan on July 14th, 2009, showing that mid-rise wood-frame buildings can be built to withstand major earthquakes.


"Thorough, detailed analysis of the data won't be available for weeks, but scientists are pleased with the initial results" said John van de Lindt, principal investigator on the test and civil engineering professor at Colorado State University.


This 40-second test, approximating a 7.5 magnitude earthquake, occurred on a seven-story condominium tower with 23 one- and two-bedroom living units. The test, held in Miki City, near Kobe, Japan, was on the world's largest earthquake shake table owned by Japan's E-Defense, a 3-D, full scale earthquake testing facility. The tower is the largest wood-frame building ever built and tested.


The U.S. building industry rarely permits wood-frame buildings in excess of five stories in earthquake-prone areas. The data gathered from this test could increase the height of these buildings and influence the design of future wood-frame construction. The government of British Columbia is particularly interested in the results of the test after enacting a new law April 1 that increases the height of wood-frame structures from four to six stories.

The seismic testing, known as the NEESWood Capstone tests, is the culmination of a four-year $1.4 million grant from the National Science Foundation to develop a new design approach for taller wood-frame buildings in earthquake-prone areas. That grant is a collaboration between five universities, including Texas A&M University, Rensselaer Polytechnic Institute, University at Buffalo, and University of Delaware.


Other contributors on the Japan project include the U.S. Forest Products Lab/Forest Service, the Provincial Government of British Columbia, FPInnovations, Maui Homes and numerous material contributors, including Stanley Bostitch, and Strocal Inc.
