Abstract

This paper describes the adhesion performance of silicone polymer structural sealant in aluminum curtain wall system. There is marked contrast between standard details and actual details of structural sealant in south Korea. Therefore, this paper explores the capacity of actual detail and repaired system. Test variables included the construction of norton tape and boundary sealant, repaired method and thickness of sealant. The one-way laminated glass panels were supported on two sides and subjected lateral load for condition of wind load applied. The test results indicated that norton tape affects the stiffness and strength of connection between glass and aluminum frame. On the other hand, the boundary sealant affects the ductility of that. There is are no significant effects of sealant thickness and repaired method on strength of connection, and observed the difference between measured capacity of specimens and design capacity of those. Therefore, the proposed reduction ratio based on measured results to reflect the actual construction details.
