About

A novel design concept for point fitted insulation glass with undercut anchors is developed. The concept considers the determination of the climate loads and proposes a verification procedure for each structural element of the insulation glass unit. For this purpose, an existing climate load model for linearly supported insulation glass is analytically extended to the static system of point fitted insulation glass units with undercut anchors. For the verification of the connection undercut anchor in glass, an existing design method for point fitted single and laminated glazing is extended to point fitted insulation glass. Component tests are conducted on the Fischer anchor and its ultimate load bearing capacity in glass is determined. A calibrated numerical model of the proposed point fitted insulation glass unit with the Fischer anchor is developed for parametric studies. Large scale tests on the proposed new point fitted insulation glass unit are run with the aim to verify the numerical model, the climate load model and the extended design method and to proof the structural integrity of the entire unit. Finally a new point fitted insulation glass unit with a suitable point fitting type and a corresponding novel design concept is developed.
