Engineering Aspects of the National Theatre

In this paper, to which the architects have kindly contributed descriptive matter, the authors describe the philosophy and the process by which the engineering works were evolved to accord with the architecture. The emphasis throughout is on integration of engineering aspects within a framework of performance requirements. The organisation of the design and related contractual aspects are touched upon. Detailed design and detailing of much of the reinforced concrete was by computer. The adequacy of bond between galvanised reinforcement and concrete containing white cement was established by tests. Structural movement is considered in relation to the detailed design of the building fabric and to noise and perceived vibration. Anti-flotation measures, both temporary andpermanent, are described. There are references to the air-conditioning systems, related problems of climatic control, and model tests which enabled satisfactory air distribution patterns to be achieved in the auditoria.
