PREDICTION FOR WIND PRESSURE RESISTANCE OF PLATE GLASS IN BUILDINGS BASED ON FAILURE PROBABILITY THEORY

摘要

New methodology using log-normal distribution was introduced in order to predict wind resistance of plate float glass in buildings based on failure probability theory. New glass surface strength parameters were obtained for reliability design mainly to failure probability 0.001 from 1926 samples of 6,8,10,12,15 and 19mm thickness. The validity was assured by comparison between experimental results of fracture tests and calculations for rectangular glass under uniform pressure. We presented new wind pressure design charts. The parameters of the charts are the aspect ratio and the glass area. The results showed that the design pressure of some cases was less than that of Notification No109 by the Ministry of Construction.
