ABSTRACT:
An apparatus for testing the strength and performance of various building structures, such as doors, windows, storm shutters and panels, under hurricane type conditions, the apparatus including a vertically supported wall and a movable test structure mounting and support assembly including a frame for supporting a building structure to be tested. The frame is movably attachable in sealed engagement to a front face of the wall, such that the test structure is disposed in close, spaced relation to the wall, creating an air tight cavity between the building structure and the front face, wherein airflow is selectively delivered to or removed from the cavity by a diverter valve along an airflow conduit connecting between an air passage hole in the wall and to a high volume, low pressure blower. A computer controls the diverter valve and monitors pressure in the cavity to selectively control and rapidly change the cavity pressure through a range of predetermined positive and negative pressure levels.
