Correspondence on Viewpoint on Why Not WL/8? by Andrew Beeby

Mr Lee: It will be seen that our paper comprises two parts, the first on design and the second on construction. My co-author for Part 2, Mr Al-Bayah, was very much looking forward to being here in person as one of the representatives of the client and to participating in the discussion. Unfortunately pressure of work in Iraq has not permitted him to come to London at this time. He has asked me to express his regrets and to pass on the good wishes of himself and his colleagues in the Government of Iraq who were concerned with the bridge for an interesting evening of technical discussion.

Microcomputers It is now nearly a year since Mr B. C. Bird asked his question about frame analysis programs for the 48K Spectrum. Since then we have had a substantial response from our readers, drawing attention to programs and problems associated with their use. This month we have three more letters. Mr K. Tregear, writing from Nizwa in the Sultanate of Oman, says that he was most interested to read, in the December issue, of the approach by Mr Bradfeld to the design of rectangular beams and slabs in accordance with the CP 110 idealised stress block.

The paper describes the development of the design of Kylesku Bridge as a sequence of design studies and decisions, from studies of the location of the new bridge and of different types of structure to final design. The new bridge is a frame with V-shaped supports. It is built in concrete and the deck is a box girder that is prestressed. The bridge was designed to be built in stages and within constraints that were specified in the contract documents. J. Nissen, K. Falbe-Hansen and H.S. Stears
