class xsect.calc.CrossSection(name, area, width=0, height=0, unit_weight=None, inertia_x=None, inertia_y=None, inertia_z=None, inertia_j=None, inertia_t=None, gyradius_x=None, gyradius_y=None, gyradius_z=None, elast_sect_mod_x=None, elast_sect_mod_y=None, elast_sect_mod_z=None, plast_sect_mod_x=None, plast_sect_mod_y=None, is_round=False, **kwargs)[source]¶

A class representing a member cross section.

Parameters:

Parameters:	name : str The name of the cross section. width, height : float The width and height of the cross section in the x and y directions. area : float The cross sectional area. unit_weight : float The unit weight of the cross section. inertia_x, inertia_y : float The moment of inertias about the x and y axes. inertia_z : float The moment of inertia about the weak principal axis. inertia_j : float The polar moment of inertia. inertia_t : float The torsional moment of inertia. gyradius_x, gyradius_y : float The radius of gyration about the x and y axes. gyradius_z : float The radius of gyration about the weak principal axis. elast_sect_mod_x, elast_sect_mod_y : float The elastic section modulus about the x and y axes. elast_sect_mod_z : float The elastic section modulus about the weak principal axis. plast_sect_mod_x, plast_sect_mod_y : float The plastic section modulus about the x and y axes. is_round : bool If True, the member represents a round cross section, such as a round or pipe. kwargs Additional keyword arguments for secondary section properties that will be stored in the object’s meta dictionary property.

name : str: The name of the cross section.
width, height : float: The width and height of the cross section in the x and y directions.

elast_sect_mod_z : float: The elastic section modulus about the weak principal axis.
plast_sect_mod_x, plast_sect_mod_y : float: The plastic section modulus about the x and y axes.
is_round : bool: If True, the member represents a round cross section, such as a round or pipe.
kwargs: Additional keyword arguments for secondary section properties that will be stored in the object’s meta dictionary property.

Examples

The dictionaries returned by the various section summary functions included in this package may be passed to the initializer using the dictionary unwrapper as shown below. This can assist in the more rapid creation of cross section objects.

>>> from xsect import angle_summary
>>> odict = angle_summary(8, 8, 1.125)
>>> CrossSection('L8x8x1.125', **odict)
CrossSection(name='L8x8x1.125', ...)

Methods

`from_aisc`(name[, metric, version, include_meta])	Initializes a cross section from the properties in the AISC database.
`from_points`(name, add[, subtract, is_round, …])	Initializes a cross section from boundary points.
