Long-Span Floors

April 18, 2012

CGA has a long history with long-span floors, primarily for fabs and flat-panel facilities, and mostly in Asia.  These have unique dynamic features, and behave differently under localized excitation from loading such as footfall.  As interest grows in non-semiconductor applications of these structures, where footfall takes on a greater importance (since heavy manufacturing equipment may not be present), it becomes more important to understand the basic dynamic properties of these floors.  Ning Tang has been leading the team of structural modelers in parametric studies of these floors, and several conference papers have been presented.
