m_n_kappa.Circle#

class m_n_kappa.Circle(diameter, centroid_y, centroid_z)#

New in version 0.1.0.

applies only for circles that are small compared to the other dimensions of the cross-section

Parameters:

diameter (float) – diameter of the circle \(d\)
centroid_y (float) – position of centroid of the circle in horizontal direction \(y_\mathrm{centroid}\)
centroid_z (float) – position of centroid of the circle in vertical direction \(z_\mathrm{centroid}\)

Rectangle: creates a rectangular geometry object
Trapezoid: creates a trapezoidal geometry object
RebarLayer: creates a number of circular objects representing a layer of reinforcement-bars

Examples

A circle object is easily instantiated as follows.

>>> from m_n_kappa import Circle
>>> circle = Circle(diameter=10, centroid_y=10, centroid_z=-10)

For building a Section the circle must only be added to a material.

>>> from m_n_kappa import Steel
>>> steel = Steel(f_y=355)
>>> section = circle + steel
>>> type(section)
<class 'm_n_kappa.section.Section'>

Methods

split(at_points[, max_widths])

check if circle is within effective width

Attributes

`area`	area of the circle
`bottom_edge`	vertical position (Z-Axis) of the bottom-edge of the circle
`centroid`
`centroid_y`	position of centroid of the circle in horizontal direction \(y_\mathrm{centroid}\)
`centroid_z`	position of centroid of the circle in vertical direction \(z_\mathrm{centroid}\)
`diameter`	diameter of the circle \(d\)
`edges`	edges in vertical direction
`height`
`sides`	edges in horizontal direction
`top_edge`	vertical position (Z-Axis) of the top-edge of the circle

split(at_points, max_widths=None)#

check if circle is within effective width

In case max_widths=None this circle is returned. Otherwise, this circle is only returned if position of the circle is smaller max_widths
