STRUCTURAL PROPERTIES OF STRUCTURAL SEALANT ABOUT 4 SIDED SSG SYSTEMS THAT WAS APPLIED TO GLASS FACADE FOR OVER 20 YEARS

Abstract

This paper indicates adhesive durability of 4 sided structural sealant which was applied to the glass facade for 20 years. Tensile tests about the structural sealant of actual facade were carried out. Results of tensile test were compared with initial data of 20 years ago. The purpose of this study is to ensure the maximum tensile strength and structural properties. Specimen was cut off from the glass unit near the top of the building facade susceptible to wind loads. As a result, most of the specimens reached maximum tensile strength at strain of 50%.
All specimens indicated a cohesive failure, also indicated a similar tensile strength compared with the initial value 20 years ago.
However, the elongation at maximum tensile strength indicated lower than initial data. Also stiffness was 2 times higher compared to the initial values.
