Structural Mechanics Behavior of Structurally Glazed Window Systems Under Dynamic Loads

A program of research at Texas Tech University has produced indepth understandings of the structural mechanics behavior of monolithic glass plates, insulating glass (IG) units and laminated glass (LG) units under the effects of lateral loads. These commonly used components of window glass systems are now being used in an innovative new window glass system called "structural glazing." In this system, the glass component (monolithic glass plate, IG unit, LG unit) is connected to the secondary structural frame of multistory buildings with a liquid structural sealant (commonly silicone) so that no mechanical device extends beyond the face of the outer-most glass plate. This research will integrate known component behaviors into an evaluation of the integrated structural mechanics behavior of structurally glazed window systems. Theoretical formulations using numerical methods will be employed. These formulations will be verified through experiment. Expected results include an improved understanding of the complex structure which a designer is asked to place on the side of a multistory building.
