This guidance is not intended to be a code of practice, but rather a principal source of information and reference. Worked examples illustrate the simple design of glass elements such as floor plates, beams and columns. Connection design is considered, as this plays a significant role in the design of glass elements. Advice on the modelling of glass structures within structural analysis computer applications is also provided, as is guidance on other issues that may influence structural behaviour, such as extreme loading conditions and fire protection.
