Paper Abstract

Holography concepts have been evaluated as nonintrusive tools that can measure earthquake effects and earthquake resistance of structures. The methods offer potential for removing limitations currently obstructing the application of advanced design techniques in civil and earthquake engineering. Methods under study can result in a capability to holographically monitor large, distant surfaces such as the face of a building, bridge foundation, liquid storage tank, or dam during interaction with geological or meteorological forces. This work included the successful demonstration that holography could be used to obtain modal information from a 3.4-meter-tall, liquid storage tank at a distance of 20 meters.
