Question

1) Model the structure in SAP2000. 2) Export axial force, shear force, and bending moment diagrams. 3) Export deformed shape. 4) How much is the deflection at J? Submit a

screenshot of the deflected shape showing the valuefor deflection at J. 5) Using the original structure, eliminate the hinge connections in the bottom chord of the trussstructure only. What is the effect of providing a continuous bottom chord on the deflection at J?Submit a screenshot of the deflected shape showing the value for deflection at J. Discuss yourresults. 6) Now, invert the truss' diagonals in the original structure (C-L instead of B-K, D-K instead of C-J, D-I instead of E-J, and E-H instead of F-I). Export axial force diagram. Are there any changesin comparison with the axial force diagram of the original truss structure in Part 2)? 7) Export the deformed shape of the truss of part 6). How much is the deflection at J? Submit ascreenshot of the deflected shape showing the value for deflection at J. Discuss your results andthe influence of this design action on the deflection at J.
