The following calculator and data pages are included in any PBV site with the tag rebar. Tag pages contain lists of vCalc items that have that tag, rebar in this case, and they provide information associated with the concept. Calculators and collections are bundled functions and data that appear on one page for convenience of the end users. Equations are single function calculator pages. Data items are either static (e.g., constants) or variable (e.g., current pricing) data items useful in equations. Datasets are tables of information. WikiClips are web content snips that are useful for recurring content such as descriptions, lists of functions or images. These can be imbedded in any other token and allow for easy maintenance and distribution of updated information.
Concrete Slab Calculator: Estimation of the amount of concrete, rebar, form boards and water needed for concrete slabs of different shapes: rectangular with squared corners, circular including semi-circle, and polygon shapes from triangular up (e.g., pentagon for 5 sides and dodecagon for 12 sided polygon).
Masonry: Includes collections of functions associated with product estimations on projects done with brick, block, concrete and rebar.
Rebar Calc: Eleven functions associated with estimating the weight and length of rebar in slabs and walls of different shapes.
Concrete Displaced by Rebar: Estimates the net weight added to a slab by adding rebar, and the reduction in concrete caused by adding rebar.
Concrete, Rebar and Forms for Wall: Computes the length or weight of rebar, the volume of concrete, or the surface area of forms for a concrete wall.
Length of Rebar in Grid: Computes the total length of rebar needed for one or more mats of rebar in a concrete slab based on slab dimensions, rebar spacing, inset from slab edge, number of mats, length of pre-cut rebar sticks, and a rebar lapping factor.
Rebar and Concrete in Slab: Computes the total length and weight of rebar and the volume and weight of concrete needed for a slab. The weight and volume calculations take into account the concrete displaced by the rebar.
Rebar Cost Estimate: Computes the total cost of rebar based on the length being purchased, length of the individual pieces being bought and unit price of one piece of rebar.
Rebar Diameter: Returns the diameter of a size of rebar.
Rebar in a Wall: Computes the length or weight of rebar in a wall.
Rebar in a Circular Slab: Estimates the total length and weight of reinforcement bars (rebar) needed for a circular shaped concrete slab.
Wall (Rebar Concrete and Forms): Computes the length and weight of reinforcement bars (rebar), volume of concrete and the surface area of forms for a wall based on the dimensions of the wall.
Rebar in an Irregular Shaped Slab: Estimates the total length and weight of reinforcement bars (rebar) needed for an irregular shaped concrete slab
Rebar Lapping Length: Computes the length overlap needed at rebar joints based on rebar size and a lapping factor.
Rebar Rough Estimate by Rebar to Concrete Density: Estimates the total weight of reinforcement bars (rebar) needed for a concrete slab based on the dimensions of the slab and a rough estimate of 80kg of rebar per cubic meter of concrete in the slab.
Rebar Rough Estimate by Percentage of Rebar in Slab: Estimates the total weight of reinforcement bars (rebar) needed for a concrete slab based on the dimensions of the slab and a percent of the slab volume in steel rebar, and a density of steel of 7,850 kg/m³.
Rebar Specs: Returns the rebar specifications for a size of rebar.
Rebar Unit Weight: Returns the kilograms per meter for a size of rebar.
Rebar Volume: Computes the total volume (V) displaced by rebar based on the length (L) and size (S) of rebar
Weight of Rebar: Computes the total weight of rebar based on the length and size of rebar.
Weight of Metal Rods: Computes the weight of a number of metal rods based on the number and dimensions of the rods.
Weight of Rebar in Grid: Computes the total length and associated weight of rebar needed for one or more mats of rebar in a concrete slab based on slab dimensions, rebar spacing, inset from slab edge, number of mats, length of pre-cut rebar sticks, a rebar lapping factor and the size of rebar.
Weight of Slab with Rebar: Estimates the weight of a rectangular slab with rebar based on the slab dimensions, rebar size and space and the known density of both concrete and rebar (steel). It also includes the individual weight of the components and the volume of concrete accounting for that displaced by rebar.
