Engineers are rightly cautious in reviewing new techniques of structural design and indeed are sometimes regarded as being too conservative in their acceptance of the results of engineering research. It seems to the writer however that any further progress in the science of steelwork design can be only made on the basis of new assumptions.
THE PRESIDENT proposed a vote of thanks to the Authors for the skill with which they had put together the information presented in the paper and the clarity of the photographs and drawings and descriptions they had given.
MR. K. C. DAVEY (Associate-Member): On the basis of the graphs shown in Fig. 10, I have found it interesting to extract some figures and consider them further, to arrive at a relative cost relationship between them as opposed to the purely weight relationship. I append below in tabulated form comparative cost and weight figures for trusses of spans considered by the author at spacings varying between 12 ft. 6 in. and 20 ft. in increments of 2 ft. 6 in. The cost is expressed in the form of equivalent units and for this purpose I have assumed that the relationship between the prices of
individual components of the building is as shown below.
