Open Discussion. Lattice Shells: Recent Experiences

This article reports experience on a number of lattice-shell roof structures we have designed recently. We are referring to structures where an open lattice is curved, either singly or doubly, so as to be able to carry load in a combination of in- and out-of-plane actions. Some published guidance on analysis exists, as do some reports on built projects which appear to have been determined by purely structural considerations. There is, however, little guidance on where to begin the design or, perhaps more importantly, what will constitute an acceptable end to the design of architecture-led projects. The choice of form for any structure must clearly address a number of issues to which the designer has to attach priority: - what space has to be enclosed? -how should the load be carried across that space? - the integration of technical subsystems into the structural arrangement - issues of overall economy -further issues, sometimes subsidiary, such as thermal performance, fire, acoustics, maintenance and daylighting M.W.
