Overview
Abstract
Structural silicone sealant is commonly used in glass fin applications, both as a weatherseal and as for structural attachment. A common concern for sealants in construction applications can be the potential for 3-sided attachment which can limit the freedom of movement in a joint. Potential design geometries were analyzed via finite element analysis to illustrate how limiting movement can be beneficial for structural elements.

Introduction
Three-sided bonding refers to the potential for a sealant joint, typically rectilinear in shape, to be in adhesive contact on three sides of the geometry which will constrain
