The Structural Engineer, Volume 62, Issue 12, 1984
Computer design programs During recent months, we have published correspondence from readers on the use of computers in engineering. We are now very pleased to have heard from Mr M. Bowden, writing from Bromley, on his experience of using a microcomputer in his practice. He writes: I read with interest your appeal in the July issue for ready-made programs which could be of use to other engineers. I was surprised to note in the August issue that only one such program had been received. Verulam
There is an increasing trend towards the refurbishment of existing buildings, many of which contain large numbers of cast-iron columns and beams. Very few data, however, have been published on methods of predicting the fire performance of cast-iron structural elements. This paper deals with the factors affecting the performance of cast iron in fire and proposes fire design parameters for use when refurbishing existing buildings containing structural cast-iron that is required to meet current Fire Regulations. J.R. Barnfield and A.M. Porter
This paper describes the design of an office block over Fenchurch Street Station in the City of London. The way in which the design was developed over a number of years is emphasised. Special considerations involved in building over a station are outlined. The alternative structural forms considered for the office block and the reasons for the adoption of a design in which most of the building spans nearly 30 m across the station are described. A detailed description of the design of 2.5-3.5 m diameter hand-dug piles and of the analysis of the interaction of these piles with 4m-deep transfer beams is given. R.F. Jacobs, S.C. Smith and E.H.F. Taylor
