Abstract: This dissertation introduces a new analysis and design approach in glazing system commonly used in curtain walling system and some important findings from the results of analysis are reported. Using the mechanical properties of glass, the non-linear finite element method can be adopted to solve practical glass/glazing structures problems. An accurate analysis is established and the strength of glass panel can be fully predicted accurately. It is shown that the current method assumes that the panel is roller supported rigidly, supported on its opposite edges and clamped along only one edge as cantilever beam. The element selected for the analysis is a flat triangular element consisting of bending and membrane components. Each element possesses three nodes with six degrees of freedom at each node. The analytical results are compared with the design charts in various national design codes of practice for glass, which verify the theory developed. According to the comparison amongst the results, it can be concluded that the proposed non-linear finite element method is a reliable analytical tool for glass/glazing structures of usual geometry, support conditions and loading. The method developed gives a more accurate result than that obtained from the simplified linear methods currently used since it allows for geometrical nonlinearly, support flexibility and stability.
