Stiffness Method for One-Dimensional Truss Elements

Assignment Task

Part

A. Calculate the structural stiffness matrix of the truss shown. Take A = 300 mm2 and E = 200 GPa.

Global coordinate system, global freedoms, and location vectors are shown in the figure below.

B. Evaluate the unknown nodal displacements and reactions for the truss of shown above using the stiffness method.

B. For the truss shown above, evaluate the member forces of each element using the stiffness method and specify whether there are in compression or tension.

D. Compare the hand calculations with the SpaceGass/ABAQUS software and comments on the comparison between them. You need to include software analysis results.

E. Compare the hand calculations with the Matlab calculations and comments on the comparison between them. You need to include screenshot of Matlab input and output files in your assignment.

Determine the support reactions for the structure shown using the stiffness method. Assume I = 200 X 106 mm2. E = 200,000 MPa.

Reconsider the beam of shown above and draw the free-body diagrams of the two elements showing all actions applied to them. Assume I = 200 x 106 mm2. E = 200,000 MPa.
