Abstract
Progressive Collapse is the total or partial failure of a structure due to the spread of local failure
from element to element throughout the structure. This research aims to determine whether the
removal of a column from a multi-story building will cause total or partial collapse. A parking
garage at Ohio State University will be used for this purpose as a case study. A 3D model of the
building to be tested was made using SAP2000(CSI). Before the demolition of the building, two
columns will be removed from the second story of the building, and various data was collected
using strain gauges, drones, and cameras. Data collected was compared to the theoretical model
and suggestions to the model will be presented. The research presented is based on the experiment
done during the demolition of the North Cannon Garage parking lot on the campus of the Ohio
State University (OSU).
Accelerometers were installed to measure the acceleration of the building during the
demolition process. Drone videos were used to assess the accuracy of the measured data, and Fast
Fourier Transform (FFT) algorithm was used to calculate the fundamental frequency of the
building. SAP2000 was used to model the North Cannon Garage structure which was used to
determine properties of the structure. The changes in the structure due to the demolition were
simulated using the program and compared to the live data recorded during the demolition.
The results show that North Cannon Garage has two different outcomes in properties
(fundamental frequency) between the model and measured values. This error stems from the
assumptions regarding the loading distribution of the building as well as lack some structural
details of the building which made it difficult to model accurately. This study is to develop
recommendations for improved modelling for progressive collapse.
