‘Tendons’ bring building in line after big quake
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 building. The inset shows the replaceable steel fuse, in yellow, at the base of the rocking frame. Behind and in front of the fuse are the vertical steel cables that pull the building back into plumb after an earthquake. During testing, the frame was sandwiched between two of the white structures.
