Effects of Human-Structure Interaction on Building Structures
Vibration Tests with Human Subjects and Concrete Blocks
|
Up until recently, the presence of human occupants was considered as added mass (weight) on the structure. Research has shown that even though they may act as dead weight for static analysis and design, they represent a dynamic system when considering vibration serviceability issues.
Several rounds of dynamic testing and measurement and analytical studies have been conducted on the VTL test structure to evaluate the dynamic effects of humans on building floor vibrations. Architecture students taking Building Structures courses participated in the tests to evaluate the human-structure interaction (HSI) effects. Estimates of the dynamic properties of groups of people have been made based on the results of these tests, using various analytical models. |
