Abstract

The influence of stress corrosion on the edge strength becomes important when designing structural glass elements. As the load duration of the design wind load (600 s) or the design temperature load is larger than the common load duration during testing the glass edge, a strength model must be used to take into account the load duration properly. In such a model, both short term parameters (i.e. the flaw geometry and depth) and stress corrosion parameters are involved. The stress corrosion parameters strongly depend upon the environment, especially the temperature and the humidity. In this study, the latter two are kept constant, for the testing at high stress rate (50 MPa/s), to determine the short term parameters as well as for the testing at low stress rate (2 MPa/s), to determine the stress corrosion parameters. The geometry factor and the stress corrosion parameters were determined for arrised and ground edges.
