Numerical and Experimental Investigations on the Stress Distribution of Bolted Glass Connections under In-Plane Loads

To calculate the loadbearing of bolted connections in glass panels under the application of in-plane loads exact knowledge of the contact mechanisms and the parameters which influence the stress distribution around the hole is necessary. At first analytical and numerical solutions of contact between a bolt and a conforming hole in a panel are formulated to determine the stress distribution. An approach for verifying the numerical model with the analytical solutions is developed. To determine relevant results for design the verified FEM-model is used to examine the influences of different parameters on the stress distribution around the hole. In addition experimental investigations are carried out in order to check the results of the FEM-calculations and the analytical solutions.
