Glass has been widely used as structural element for many prestigious buildings in big cities but its design is not well understood by most engineers. Glass supporting structures require more carefully consideration on its interaction with the brittle glass materials and pre-tensioned high strength trusses using alloy steel bar require the consideration of its behaviour under the influences of support movement, temperature change and wind loads. The resistance of lateral wind pressure of the system makes use of high tension force coupled with the large deflection effect, both of which are affected by many parameters not generally considered in conventional structures. In the design, one must therefore give a careful consideration on various effects such as support movement due to live loads and material creep, temperature change, pre-tension force and wind pressure. It is not uncommon to see many similar glass wall systems fail in the wind load test under a 50-year return wind pressure. This paper presents a rigorous analysis and design of this type of structural systems used in some of the projects in Hong Kong. The considerations and analysis techniques are believed of values to engineers involved in the design of the structural systems behaving nonlinearly.
