In projects involving swimming pools with structural glass, ABT Consulting Engineers has faced similar design requirements: maximal transparency, proper detailing, 100% water tightness and robust behavior. ABT developed a straightforward detailing to satisfy these requirements. The concept is applied in the glass swimming pool of the 900 Mahler project, where the layered and heat strengthened glass panes were designed with specific attention to the appropriate type of interlayer and functional, durable and practical support detailing. The implementation of a clear safety philosophy, backed by an executed risk analysis, led to a glass structure which functions in all circumstances. The panes were structurally analyzed on strength and stiffness with finite element software, with extra focus on the appropriate properties of the support conditions. The concept is ready to be applied in similar glass pools.
