Performance-based seismic design is on a roll, thanks to recent, first-of-their-kind shake-table tests that proved the viability of a “rocking” braced frame that moves seismic design beyond life ...

SAN DIEGO (AP) — Researchers at the University of California, San Diego rocked and rattled a six-story steel frame building on a giant shake table Wednesday to see how the structure would withstand ...

Structural engineers at UC San Diego were waiting to see how a tall building, made from recycled steel, would react in a 6.9 magnitude earthquake. The earthquake shake table was ready to go as the ...

"Three, two, one!” The tallest steel-framed building ever tested on an earthquake simulator started moving slowly, swaying and twisting. The 10-story, 100-foot structure was experiencing simulations ...

A 40-second test in Japan on the world’s largest shake table demonstrated for the first time that wood-framed mid-rise buildings can be built to withstand major earthquakes, say researchers. The ...
