This Thesis is about the process of rehabilitating a shake table for use in seismic analysis of small-scale models in the School of Architecture. Labview 8.0 Student Edition was used to write the controlling program for the shake table. -- In order to test seismic response of a prototype building, a 7-story reinforced concrete building was modeled in piano wire and plywood and tested on the shake table. The shake table recorded data from an accelerometer mounted on the model. The model was built to have the same resonant frequency as the prototype building. -- The model clearly shows modal forms and shows exaggerated deflection, as well as torsion caused by modeling inconsistencies. Reactions in the model correlate to the prototype. A model on a shake table is useful to the School of Architecture as a teaching tool to visually highlight the effect strong ground motion can have on a building.
