Determination of Adhesives Properties for Non-linear Numerical Simulation of Structural Steel-Glass Connections

In the construction of façades, connections between glass and glass as well as other materials with varying properties, e.g. metals, are currently designed with, inter alia, the application of adhesives. The related analytical evaluation of the load bearing characteristics of these kinds of assemblies requires the correct determination of the adhesives’ properties; knowledge in this field is still incomplete. Therefore an extensive test campaign on the load bearing and displacement behaviour of common structural silicone and UV-acrylic was carried out with the aim, to identify appropriate models to describe their properties under quasi-static loading and for their implementation in numerical analyses. The test program, comparisons between the different adhesive materials and a summarised outcome will be presented in this paper.
