Calculating nodal displacements using Local and Global Stiffness Matrix EXAMPLE (Part 2 of 2)

In this video I use the local stiffness matrices of each member to find the global stiffness matrix then the nodal displacements. ITS SIMPLE!! STEP 1 Label all the nodal displacements with the appropriate annotation in order. STEP 2 Write out the local stiffness matrix formula STEP 3 Evaluate the sin and cosine of the given angles at each node and start constructing the associated local stiffness matrix STEP 4 Depending on how many members you have, construct the global stiffness matrix by adding the corresponding components that "overlap" with each local stiffness matrix into the global stiffness matrix.
