Abstract
Holography concepts have been evaluated as nonintrusive tools that can measure earthquake effects and earthquake resistance of structures. The methods offer potential toward the application of advanced design techniques in civil and earthquake engineering. Our study produced methods to holographically monitor large, distant surfaces, which could be used to inspect buildings, bridges, storage tanks, or dams during interaction with geological or meteorological forces. This work included the successful demonstration of holography in obtaining modal information of a 3.4-m-tall liquid storage tank at a distance of 20 m.
