This paper deals with an ‘umbrella ’structure, illustrated in Fig I , to provide support to a new roof deck over a series of existing two storey flat-roof buildings. This solution was adopted after investigation of various options, such as replacing the existing bituminous-felt membrane with a modern fabric or by placing a lightweight pitched roof fixed to the existing structure. Consideration was also given to a new-build solution, but costs were prohibitive. This project is being carried out under the GC Works I Form of Contract and costs are in the region of £6M. B. Taylor
The design of elements, which are part of a continuous slab or structural framework, to withstand fire is a complex problem. In this paper, the method of plastic analysis is used to determine the failure capacity and fire resistance of an internal span of a continuous concrete slab. Failure loads are evaluated using sectional plastic moments derived on the basis of Eurocode 2 recommendations for material properties at elevated temperatures. The analysis is compared with results of a test programme on simply supported and continuous concrete slab strips both at ambient temperature and under a fire regime. The plastic analysis predictions offire resistance times in a post test analysis were found to be quite accurate. In the test programme half-scale models were utilised and in the fire testing an equivalent model fire curve was derived, based on other work, which produced similarity of thermal responses in the model specimen.
