Research output: Contribution to conferencePaper


The methods for determining load sharing of insulating glass units in commonly used glass strength standards employ linear theory. This paper presents a comparison of linear and non-linear calculations for load sharing of double and triple glazed insulating glass units. The major factors varied in the investigation are constructions, rectangular dimensions, glass lite thicknesses, and initial airspace volumes. Applied external load versus load sharing percentage curves are presented for select insulating glass unit specimens. Figures in this paper show the load sharing trends of various similarly loaded insulating glass units, and the results presented in this paper suggest the difference between the linear and non-linear method for load sharing in IGUs.
