Load-bearing adhesives are capable of transmitting permanent, short-term and impact loads. They enable new and innovative designs. However, due to the aging behaviour of the bonded joint, envi-ronmental influences have to be taken into account in the design. This article shows the development of a new type of stiffening balustrade which is in-plane loaded and made of glass. Bonding makes a significant contribution to the transfer of loads acting over different periods of time. Part of the devel-opment is an experimental test program as well as a numerical simulation with solid elements and springs. The result is a ready-to-use bonded stiffening element and its design concept.
