Culvert structure having corrugated ribbing support

Abstract: A low-profile culvert structure comprising in combination, a plurality of arch-shaped corrugated structural metallic sheets secured to each other in such a manner as to form an elongated shell having typically a low rise to span ratio, and a plurality of transverse reinforcing ribs, each in the form of a corrugated metallic sheet. The transverse reinforcing ribs are secured to said shell at intervals along the length thereof, preferably to both the interior and exterior of the elongated shell.

Effect of recycling on residuals, processing, and properties of carbon and low-alloy steels

Abstract: Because of the continuing increase in electric furnace steelmaking, which is a scrap-intensive process, and also in view of future new sources of scrap, such as municipal solid wastes, it is important to develop more knowledge about: (a) the effects of residual elements on steel, (b) processing strategies for producing high-residual steels, and (c) products in which residuals could be used to advantage. This review will first identify the important residual elements and the trends in their use and levels in steels. The effect of these elements on the processing phenomena and product properties of carbon and low-alloy steels will be discussed in detail. These phenomena and properties include hot shortness, scale adherence, room temperature tensile properties, impact resistance, and hardenability. Also discussed are examples of specific problems that residual elements present, both now and with emerging trends, for steel processing and applications, and the ways of using residuals to advantage.
