The Structural Engineer

1) The formation of the Institution’s ad hoc committee (chaired by David Doran (F)) on engineering implications of alkali-silica reaction in concrete structures was announced in The Structural Engineer, December 1986. Its brief is to prepare early interim guidance on the identification, engineering appraisal and management of structures affected by alkali-silica reaction. It is envisaged that more coherent and comprehensive guidance will be prepared in about 2 years, when further results of current appraisals and research investigations are available.

In the Spring of 1983, architects, Brian Taggart Associates, commenced work on the design of eight pavilions. These enabled the Borough Council of Basingstoke & Deane to offer small, rentable work bases for industrial or business use. Peter R. Brett

The relationship between this Institution and the Institution of Civil Engineers has been discussed several times in the last few years. Clifford Evans, when President, stated that he thought that structure for the building industry, and its attached technology, was the primary area of interest of our Institution and that the Institution of Civil Engineers should leave that body of knowledge to us. Alastair Paterson, when President, suggested that we should consider a merger of our Institution with the Civils, though that did not receive Council or wider approval at that time.

In October 1984 the Minister for Housing & Construction announced that the Building Research Establishment would undertake a programme of investigations of dwellings constructed from large-panel systems (LPS). The structural adequacy and durability of large panel system dwellings, published recently, results from those investigations and is intended to assist local authorities and their consultants in appraisal of LPS dwellings. A summary sheet (IP8/87) has also been published. This states that the principal findings and conclusions from BRE’s own site investigations and from an analysis of private-consultants’ reports are: ‘No major structural failure of a LPS building in the UK has been reported since the programme of appraisal and strengthening of LPS building was carried out following the collapse of Ronan Point in 1968. The BRE has found no LPS building

I should like to respond to some of the criticisms and observations published in The Structural Engineer in February regarding my ‘viewpoint’. Philip Beadle

This paper describes the structural design and construction of the Queen Elizabeth II law court, situated in Birmingham. The particular problems of crown court planning as they affected the structural design, the solution produced, and the execution of the detailed design, are discussed. The construction stage is also described and includes the results of the dynamic analysis of the piled foundations. R.A. Davis

It is suggested that the use of reinforced concrete based on scientific analysis began in the decade 1875-1885. Before that, the medium had been used intuitively, for about 30 years, with a wide range of cements. This use in its turn had developed from the need to provide structural iron with nonstructural fireproof encasement. From 1885 to 1910 there was a rapidIy increasing perception of the behaviour and potential of reinforced concrete. The paper foIIows the emergence of this new building medium, from the middle of the 18th century, when the intimately-bonded combination of metal and concrete of any form held no meaning in building, to 1910 when it had become universally known and was being used much in the manner accepted today and in most of the form now employed.

Keith White will succeed Professor Edmund Happold, FEng, as President of the Institution 1987-1988 at an Ordinary Meeting at Institution headquarters on 1 October 1987. The handover ceremony begins at 6.oopm, when Mr White will give his Presidential Address ‘The Institution today and tomorrow?’, the full text of which will be published in The Structural Engineer in November.

Shear resistance of bend-up bars There has been quite a response to Mr Porter’s query (July) regarding the apparent anomaly in the concrete Code, in that it appears to make the shear resistance Vb, independent of the bend-up bar spacing Sb. Verulam
