Text of a letter from the President of the Institution, Mr. D.A.G. Reid, CBE and the Chairman of the Council of Engineering Institutions, Sir Robert Wynne-Edwards, dated l2 May 1966: ‘Dear Minister, For some months past the Council of this Institution, together with the Chairman and some members of the Council of Engineering Institutions, have been giving anxious consideration to matters associated with the building of the new County Hall for the County of Bedford. You will, we are sure, be familiar with the case.'
It is often found in the design of bridges, and sometimes in the design of floor slabs and beams for buildings, that the spans are of uniform section and symmetrically placed. C. Lawrence
The paper describes tests on twenty-seven Lytag concrete columns. Sixteen of the columns were reinforced with varying percentages of square twisted steel and the remaining eleven were unreinforced. It was found that, although the ultimate loads of reinforced Lytag concrete columns are slightly less than those of equivalent gravel concrete columns, the load factors are satisfactory. It is therefore safe to design reinforced Lytag concrete columns with the permissible stresses specified in CP l14 (1957). C.O. Orangun
