Beams diagrams for shear, moments, angle, and deflection Python Application Script

This applications is python-based to perform engineering analysis on beams with diagrams for shear, moments, angle, and deflection

Perform engineering analysis on beams with diagrams for shear, moments, angle, and deflection including 3D plots.

Python code - This application requires knowledge of Python installation and code execution.

﻿Sample Code

E = 207 * 10 ** 6
L = 1.0
CS = CrossSection ( CrossSectionTypes . CIRC , [ .01 ])
B = Beam ( L , E , crossSection = CS )
B . addPointLoad ( L / 2 , - 20 , 45 )
B . addPointLoad ( L , 11 , 45 ) B . addDistributedLoad ( 0 , L , - 2 , 45 ) B . addBoundaryCondition ( L / 2 , BoundaryConditionTypes . ANGLE , 0 )
B . addBoundaryCondition ( L , BoundaryConditionTypes . DEFLECTION , 0 )
B . runAnalysis ( outputToFile = True )

Requirements

• Currently reactions are not solved for...
• All loads and reactions must be inputted
• Boundary conditions currently required
• one angle AND one deflection value
• OR two deflection parameters
• Beam weight is not accounted for by default
• represent it with a distributed load
