DYNAMIC PROPERTIES OF SEALING MATERIAL IN GLASS WALLS

Recently large scales of glass wall structures have been constructed in urban complexes, as entrance halls or atrium walls, however, their dynamic characteristics under seismic vibrations are yet to be clarified. The sealing materials in-filled between the glass panels are considered to be the main factor for the stiffness and damping of such glass structures. In this paper, detailed dynamic experiments on the sealing material are carried out, and their dynamic characteristics under various frequencies, strains, and temperatures are verified. Also the own-period and damping ratios of detailed glass wall models are estimated by time-history analyses.
