SAN DIEGO - A two-story cross-laminated timber (CLT) structure was subjected to seismic forces produced by a 1994 6.7 Northridge earthquake. The engineered simulation is expected to reveal ways in which tall wood buildings could survive damaging earthquakes.
Workers constructed a 22-foot tall wood test structure on UC San Diego's shake table, a device for shaking structural models or building components with a wide range of simulated ground motions, like earthquakes.
A manufacturer of cross laminated timber panel recorded seismic testing of its material in a two-story building placed on a giant shake table.
Led by the Colorado School of Mines (CSM), the new test will examine the viability of constructing quake-resistant CLT buildings that could be as tall as 20 stories high.
“We are working to minimize the amount of time buildings are out of service after large earthquakes," CSM engineer Shiling Pei said in a statement. "We are also focused on cutting the costs required to repair them.”
