Deformed bars and welded wire fabric have settled into their general patterns of usage. Many of these patterns are wasteful of materials. How can materials be conserved in manufacture, design and construction? The answer are presented separately here for the two materials. To make the best of the steel shortage the single most important step is to use Grade 60 rebars. If the strength design method is used this procedure alone will save 20 to 25 percent of the steel that would have been needed using Grade 40 rebars. With the working stress design method even more steel would be saved. To elaborate on means of saving reinforcing steel, the following checklist is offered to designers. Walls- consider using unreinforced walls wherever loads are minimal. Columns and footings- use the largest size bar possible, or use bundled bars, to minimize the number of ties per set. Piers- consider unreinforced piers where loads are minimal and piers are short, that is, where the height to width ratio is three or less. Slabs- shrinkage and temperature bars in slabs on grade are not required by ACI 318=71. Control joints are a prudent substitute. A number of further economies can be realized by the designer and detailer. Since the designer had a wide option of wire sizes and spacings, most reinforcement can be designed extremely closely with welded wire fabric. One aim of detailing should be the reduction of the number of sheet sizes and wire sizes to the least practical number consistent with structural requirements, economy, and construction practice. Recently, a consulting engineer was asked to review the plans for a three story structure. The building was moderate in size and had flat plates of the flooring system. The designer had used over 20 different system of fabric. Needless to say, only about three of these styles were used to any great extent.
