Investigating The Effects Of Various Crowd Characteristics On The Dynamic Properties Of An Occupied Structure, Robert Joseph Firman Iii Jan 2010

Investigating The Effects Of Various Crowd Characteristics On The Dynamic Properties Of An Occupied Structure, Robert Joseph Firman Iii

Honors Theses

One of the challenges for structural engineers during design is considering how the structure will respond to crowd-induced dynamic loading. It has been shown that human occupants of a structure do not simply add mass to the system when considering the overall dynamic response of the system, but interact with it and may induce changes of the dynamic properties from those of the empty structure. This study presents an investigation into the human-structure interaction based on several crowd characteristics and their effect on the dynamic properties of an empty structure. The dynamic properties including frequency, damping, and mode shapes were …
