Components for Local Load Transfer at Glass Compression Layers

摘要

The TU Dresden is decisively involved in the development of a sustainable and transparent glazedrnroof structure. The designed transparent space grid structure is based on a conventional steel spacerngrid, in which all steel members of the compression layer are replaced by glass panes. The glazingrntransfers large in-plane forces and serves as roof covering. Prerequisite for these structures is thernload application of significant compression forces into brittle glass edges. The intended detailrndesign requires a contact material, which is softer than glass while providing a high compressivernstrength, low creeping and a large working temperature range. Different metal alloys and polymersrnwere tested with regard to their compressive strength. Tests on their creeping behaviour started inrn2008.
