Two distinct sections of research are presented in this thesis. The first section
summarizes research conducted on laboratory-built floors. Floors were built and tested to
determine the plywood contribution to increasing the bending stiffness, number of joists
effective in resisting applied load, and calculation of fundamental frequency. The second
section summarizes research conducted on in-situ floors. Procedures were developed to
numerically integrate acceleration and velocity data to obtain displacement values. Tests
were conducted on 86 subjectively rated wood floors to determine average frequency and
peak displacement values. From these tests, a design criterion was developed to predict
acceptability of a wood floor system to vibrations.
