Weighing steel reinforcement is an important part of structural design and calculation. Calculating the weight of reinforcement in per-meter units is a key step in the design process. Steel reinforcement calculations must be performed for beams, slabs, and columns. In order to calculate the per-meter weight, we must first determine the type of structure being reinforced.
The density of steel varies from 7850 kg/m3 to 8050 kg/m3. This density is used to calculate the unit weight in design standards. The design standard EN 1991-1-1 Table A.4 specifies the unit weight of steel as 78.5 kN/m3. For steel bars, the most common diameters are 6mm, 8mm, 10mm, and 12mm.
The simplest method to determine the weight of steel reinforcement is through the RC elemental breakdown. However, this method is not the most accurate. It requires considerable experience and a Standard Method of Measurement. It gives a rough indication of how much steel is needed per cubic meter, but is not a definitive guideline.
When estimating the WEIGHT OF STEEL reinforcement, it is important to determine how much steel will be required. Once you have the total amount of steel needed, you can calculate the total weight of the steel bars. The formulas below will help you estimate the weight of a steel bar by using a few different bar sizes.
The weight of steel per meter varies. A 6mm steel bar will weigh 0.265 kg per square foot, whereas an eight-ten-millimeter steel bar will weigh 0.167 kg. Similarly, a sixteen-inch steel bar will weigh 1.08 kg per square foot.
Steel is stronger than concrete and is less prone to cracks than concrete. It can withstand up to 8% more force than concrete and is ductile. However, it has very little tensile strength. Unlike concrete, steel can withstand a five to eight-percent plastic deformation. This composite action makes it ductile and can withstand small cracks.
Steel is a common sight on the construction site. It is composed of iron and carbon, with varying percentages of other metallic elements. The addition of nickel and cobalt alters its properties. In addition to steel’s mass to volume ratio, it is magnetic. Its unit weight is approximately 7850 kg per cubic meter, and its strength is eight-five kN/m3.
