ConcreteBeam Usage ExampleΒΆ

How to create a beam:

In [1]: import fconcrete as fc

In [2]: n1 = fc.Node.SimpleSupport(x=0, length=20)

In [3]: n2 = fc.Node.SimpleSupport(x=400, length=20)

In [4]: f1 = fc.Load.UniformDistributedLoad(-0.6, x_begin=0, x_end=400)

In [5]: concrete_beam = fc.ConcreteBeam(
   ...:     loads = [f1],
   ...:     nodes = [n1, n2],
   ...:     section = fc.Rectangle(30,80),
   ...:     division = 200
   ...: )
   ...:

You can use all properties and methods of the ConcreteBeam Class including Beam Class such as plot shear diagram, momentum, etc. See examples in Beam usage example.
