Seismic Bridge
US Patent:
5537790, Jul 23, 1996
Filed:
Feb 9, 1994
Appl. No.:
8/193720
Inventors:

Abstract:
A seismic bridge for bridging and providing pedestrian access across a seismic joint between two building parts has a first end unit with a floor pivotally connected to one of the building parts and a second end unit with a floor pivotally connected to the other building part. A corridor sleeve unit, also having a floor, is slidably connected to each of the first and second end units. During relative motion between the two building parts, such as during an earthquake, the bridge can accommodate relative motion between the building parts within a predefined range, while still maintaining the structural integrity of the bridge. The bridge also includes centering means for centering and properly positioning the corridor sleeve unit with respect to the first and second end units. The centering means uses springs in combination with a plurality of frames which are slidably connected to each other to maintain the appropriate distance between the end units and the corridor sleeve unit.
