Description

Consider a Beam Element system, as the one shown in the figure below. Use the “Simplex

Beam Element Matrix and the linear spring matrix to solve for the displacements and reactions

at the supports.In developing your solution, make sure that you show the following:

– Write the element matrices of each and all elements (including the springs)

– Write the Global Matrix in the sequential order

– Rewrite the global matric with Partitions for Fixed and Free degrees of freedom

– You can invert the “D” matrix using any solver (MATLAB, Mathematica or any other

solver)

– Write the solution (Displacements and reactions) clearly and Box it.

– Do a shear and moment diagram of each beam set (upper and lower sets)

Pr. 1. Consider a Beam Element system, as the one shown in the figure below. Use the “Simplex

Beam Element Matrix and the linear spring matrix to solve for the displacements and reactions

at the supports.In developing your solution, make sure that you show the following:

– Write the element matrices of each and all elements (including the springs)

– Write the Global Matrix in the sequential order

– Rewrite the global matric with Partitions for Fixed and Free degrees of freedom

– You can invert the “D” matrix using any solver (MATLAB, Mathematica or any other

solver)

– Write the solution (Displacements and reactions) clearly and Box it.

– Do a shear and moment diagram of each beam set (upper and lower sets)

Before you start, Make a table for the following parameters and loads

E1= E2= E3= E4 = E5 = 10 x 106 psi

L1, L2, L3, L4, L5 = Your choice (use inches)

I1= I2= I3 = Your Choice for a rectangular cross section, sketch it (use inches2

)

I4= I5 = Your Choice for a circular cross section sketch it (use inches2

)

Kspring = Your Choice (use lb/in)

F2 and M3= Your Choice (use lb and lb-in respectively)
