Parameters

ID	(int): Unique fiber section ID.
b	(float): Width of the section.
e	(float): Concrete cover.
D_bars	(float): Diameter of vertical reinforcing bars.
Ay	(float): Area of one vertical reinforcing bar.

unconf_mat_ID	(int): ID of material model that will be assigned to the unconfined fibers.
conf_mat_ID	(int): ID of material model that will be assigned to the confined fibers.
bars_mat_ID	(int): ID of material model that will be assigned to the reinforcing bars fibers.
discr_core	(list): List with two entries: number of subdivisions (fibers) in the circumferential direction (number of wedges), number of subdivisions (fibers) in the radial direction (number of rings) for the confined core.
discr_cover	(list): List with two entries: number of subdivisions (fibers) in the circumferential direction (number of wedges), number of subdivisions (fibers) in the radial direction (number of rings) for the unconfined cover.
alpha_i	(float, optional): Angle in deg of the first vertical rebars with respect to the y axis, counterclockwise. Defaults to 0.0.
GJ	(float, optional): Linear-elastic torsional stiffness assigned to the section. Defaults to 0.0, assume no torsional stiffness.
