1. Python commands:

1.1 Creating Beam Object

Access

from NUTS_calkit import NUTS_calkit as nc
nc.Beam()

<<<<< Required arguments >>>>>
d: Section depth
w: Section width
ft: Flange thickness
wt: Web thickness
fpl: Plastic strength of beam
E: Elastic modulus
G: Shear modulus
alfa: Thermal expansion L: Length
t_dist: Temperature distribtuion in the section
Dataformat: [temperature, ratio of the distance from beam top/section depth], 20C <= temperature <= 1200C.
Example: [[1100,0],[700,0.1],[500,0.2],[400,0.3],[350,0.4],[325,0.5],[300,0.6],[300,0.7],[300,1]]

<<<<< Optional arguments >>>>>
*For Beam.Mcr_t_bow() alpha: Coefficient of thermal expansion

<<<<< Returning objects >>>>>
Beam object
