Detailed Description

Class that is the children of UVC that retrieve calibrated parameters from UVC_calibrated_parameters.txt.

The file text can be modified by adding more calibrated parameters.

Parameters

UVC	Parent class.

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
		int	ID,
		str	calibration,
			fy = -1,
			E = -1
	)

Constructor of the class.

It retrieve the parameters from UVC_calibrated_parameters.txt and pass them in the parent class.

Parameters

ID	(int): Unique material model ID.
calibration	(str): Label of the calibration parameter set. The options are:

'S355J2_25mm_plate' \n

'S355J2_50mm_plate' \n

'S355J2_HEB500_flange' \n

'S355J2_HEB500_web' \n

'S460NL_25mm_plate' \n

'S690QL_25mm_plate' \n

'A992Gr50_W14X82_web' \n

'A992Gr50_W14X82_flange' \n

'A500GrB_HSS305X16' \n

'BCP325_22mm_plate' \n

'BCR295_HSS350X22' \n

'HYP400_27mm_plate' \n

Parameters

fy	(float, optional): Yield strength. Defaults to -1, e.g. taken equal to the one given in the calibration parameter set.
E	(float, optional): Young modulus. Defaults to -1, e.g. taken equal to the one given in the calibration parameter set.

Exceptions

NegativeValue	fy needs to be positive if different from -1.
NegativeValue	E needs to be positive if different from -1.
NameError	calibration needs to be equal to the label of one of the set of calibrated parameters.

Reimplemented from UVC.

Reimplemented in UVCCalibratedRCCircShape, UVCCalibratedRCRectShape, UVCCalibratedSteelIShapeFlange, and UVCCalibratedSteelIShapeWeb.
