Investigations on Linear Silicone Joints for Glass-Metal Elements with Composite Structural Behavior

A trend towards adhesive connections instead of mechanical ones can be observed for transparent facades in recent years. Furthermore, research efforts are made to increase the efficiency regarding material use by designing systems with composite structural behavior. In this article, experimental and...
