Center to Center Spacing given Shortest Distance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Center to Center Spacing = 2*sqrt((Shortest Distance+(Diameter of Longitudinal Bar/2))^2-(Effective Cover^2))
s = 2*sqrt((acr+(D/2))^2-(d'^2))
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Center to Center Spacing - (Measured in Centimeter) - Center to Center Spacing is the c-c spacing of longitudinal spacing obtained from the section of the member.
Shortest Distance - (Measured in Centimeter) - Shortest Distance is described as the distance from selected level on the surface to the longitudinal bar.
Diameter of Longitudinal Bar - (Measured in Centimeter) - Diameter of Longitudinal Bar shall not have a cover less than 40 mm or the diameter of the bar whichever is more.
Effective Cover - (Measured in Centimeter) - Effective Cover is the distance from exposed surface of concrete to the centroid of main reinforcement.

STEP 1: Convert Input(s) to Base Unit

Shortest Distance: 2.51 Centimeter --> 2.51 Centimeter No Conversion Required
Diameter of Longitudinal Bar: 0.5 Meter --> 50 Centimeter (Check conversion here)
Effective Cover: 50.01 Millimeter --> 5.001 Centimeter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

s = 2*sqrt((acr+(D/2))^2-(d'^2)) --> 2*sqrt((2.51+(50/2))^2-(5.001^2))

Evaluating ... ...

s = 54.1032383134318

STEP 3: Convert Result to Output's Unit

0.541032383134318 Meter -->54.1032383134318 Centimeter (Check conversion here)

FINAL ANSWER

54.1032383134318 ≈ 54.10324 Centimeter <-- Center to Center Spacing

< 7 Calculation of Crack Width Calculators

Average Strain at Selected Level given Crack Width

Go Average Strain = (Crack Width*(1+(2*(Shortest Distance-Minimum Clear Cover)/(Total Depth-Depth of Neutral Axis))))/(3*Shortest Distance)

Minimum Clear Cover given Crack Width

Go Minimum Clear Cover = Shortest Distance-((((3*Shortest Distance*Average Strain)/Crack Width)-1)*(Total Depth-Depth of Neutral Axis))/2

Crack Width on Surface of Section

Go Crack Width = (3*Shortest Distance*Average Strain)/(1+(2*(Shortest Distance-Minimum Clear Cover)/(Total Depth-Depth of Neutral Axis)))

Depth of Neutral Axis given Crack Width

Go Depth of Neutral Axis = Total Depth-(2*(Shortest Distance-Minimum Clear Cover)/(3*Shortest Distance*Strain)-1)

Effective Cover given Shortest Distance

Go Effective Cover = sqrt((Shortest Distance+(Diameter of Longitudinal Bar/2))^2-(Center-to-center Distance/2)^2)

Center to Center Spacing given Shortest Distance

Go Center to Center Spacing = 2*sqrt((Shortest Distance+(Diameter of Longitudinal Bar/2))^2-(Effective Cover^2))

Diameter of Longitudinal Bar given Shortest Distance

Go Diameter of Longitudinal Bar = (sqrt((Center-to-center Distance/2)^2+Effective Cover^2)-Shortest Distance)*2

Center to Center Spacing given Shortest Distance Formula

Center to Center Spacing = 2*sqrt((Shortest Distance+(Diameter of Longitudinal Bar/2))^2-(Effective Cover^2))
s = 2*sqrt((acr+(D/2))^2-(d'^2))

What does Effective Cover mean?

The effective cover is the distance between the exposed concrete surface to the centroid of the main reinforcement. ( or) The effective cover is the distance between the outermost compression face of RCC to the center of the area of main reinforcement in tension. It is required for protecting the rebar against erosion and providing protection against fire. Clear cover is mainly the actual distance from the bottom of fiber to the bottom level of the reinforcement.

What is Centre to Centre Spacing?

Centre-to-centre distance (c.t.c. distance or ctc distance) is a concept for distances, also called on-center spacing (o.c. spacing or oc spacing), heart distance, and pitch. It is the distance between the centre (the heart) of a column and the centre (the heart) of another column.
