VIBRATION CHARACTERISTICS OF WALLS AND A PLATE GLASS WINDOW REPRESENTATIVE OF THOSE OF A WOOD-FRAME HOUSE

摘要

Experimental studies of the vibration characteristics of structural components representative of wood-frame house construction were conducted with the use of various face sheet materials. Mechanical excitation was used, and measurements of acceleration response, natural frequencies, and nodal patterns were performed. Results indicate that the wall sections and the complete wall did not act as a unit in responding to sinusoidal vibration inputs. Calculated frequencies of the components that account for this independent behavior of the studs and face sheets agreed reasonably well with experimental frequencies. Experimental vibrations of the plate glass window agreed with the calculated behavior, and responses of the window exposed to airplane flyover noise were readily correlated with the test results.
