ModifiedIMK

Parent class.

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
			ID,
		SteelIShape	section,
			N_G = 0,
			K_factor = 3,
			L_0 = -1,
			L_b = -1,
			Mc = -1,
			K = -1,
			theta_u = -1,
			safety_factors = False
	)

Constructor of the class.

It passes the arguments into the parent class to generate the combination of the parent class and the section class SteelIShape. Every argument that is optional and is initialised as -1, will be computed in this class. The copy of the section passed is stored in the member variable self.section.

Parameters

ID	(int): ID of the material model.
section	(SteelIShape): Object that store informations for a steel I shpae section.
N_G	(float, optional): Gravity axial load. Defaults to 0.
K_factor	(float, optional): Rigidity factor. Defaults to 3 (assuming cantilever).
L_0	(float, optional): Position of the inflection point. Defaults to -1, e.g. computed as the total length, assuming cantilever.
L_b	(float, optional):Maximal unbraced lateral torsional buckling length. Defaults to -1, e.g computed as the total length, assuming cantilever with no bracing support.
Mc	(float, optional): Capping moment. Defaults to -1, e.g. computed in ComputeMc.
K	(float, optional): Residual strength ratio. Defaults to -1, e.g. computed in ComputeK.
theta_u	(float, optional): Ultimate rotation. Defaults to -1, e.g. computed in ComputeTheta_u.
safety_factors	(bool, optional): Safety factors used if standard mechanical parameters are used (not test results). Defaults to False.
