Buildings that rock during an earthquake and return to plumb would withstand seismic shaking better than structural designs commonly used in vulnerable zones of California and elsewhere. A ...

Illustration: Schematic diagram of the rocking frame set up for shake-table testing. The steel-braced frame is shown in red. The white structure behind the frame simulates the weight of a three-story ...

This is a schematic diagram of the rocking frame set up for shake-table testing. The steel-braced frame is shown in red. The white structure behind the frame simulates the weight of a three-story ...

Computer modeling shows this alternative design for a three-story building frame suffers less damage than current designs used in earthquake-prone areas. Columns of the steel-braced frame are tethered ...
