Mr. Brian Scruby (Chairman): ‘ A point that occurred to me when reading your paper was that when I went to America a few years ago I saw some buildings which I thought were rather typical of the industrial side of American building and which seemed to be designed for a specific period of time.

As most of the piers of viaducts act as cantilevers for horizontal loads at top, requiring greater rigidity at base along longitudinal direction, a new type of structural element is suggested which is expected to serve as pier with reasonable efficiency. Rigidity at bottom is not much needed if piers act as a whole, being framed by top capping beam. S.K. Kundoo and B.B. Maiti
