C8x11.5 Channel Size and Dimensions
The dimensions and specifications of C8x11.5 structural steel channel are as follows:
|Flange Width||2.260 in|
|Flange Thickness||0.390 in|
|Web Thickness||0.220 in|
In addition to the information listed above, the inside flange surfaces of “C” shapes have a slight angle or slope. The nominal slope of the inside flange surfaces is 16.7% or 9.46 degrees.
American standard channel forms are designated by their depth x weight. The C8x11.5 designation means that the channel weighs 11.5 pounds per foot. Therefore, a 10-foot length of C8X11.5 channel weights 115 pounds and a 20-foot section of C8X11.5 weighs 230 pounds.
C8x11.5 to Metric
The closest metric equivalent to C8x11.5 is C200x17.1, which has the following specifications:
|Flange Width||57 mm|
|Flange Thickness||9.9 mm|
|Web Thickness||5.6 mm|
C8x11.5 Section Properties
C8x11.5 Area Moment of Inertia
The area moment of inertia (or second moment of area) for a C8x11.5 channel about the X-axis can be calculated from the following formula:
The area moment of inertia of C8x11.5 about the X-axis is approximately 32.4 in4 (13.5×106 mm4).
C8x11.5 Section Modulus
The elastic section modulus for a C8x11.5 channel about the X-axis is calculated from the equation below:
The elastic section modulus for a C8x11.5 channel about the X-axis is approximately 8.11 in^3.
The properties of C8X11.5 channel are specified by ASTM A6 “Standard Specifications for Rolled Structural Steel Bars, Plates, Shapes and Sheet Piling”
