The closed form solutions for ?max and Mmax are given on page 16.1-276 for several axial loads. Figure C-C2.2 summarizes the results for the first benchmark problem and Figure C-C2.3 summarizes the second. I want you to conduct second order analyses for both benchmark cases, using MASTAN or any other structural analysis software you choose. Here is how I want you to do it:

• Apply a uniform load of 0.2 k/ft on the first benchmark problem (as shown in the figure).
• Apply a horizontal wind load of 1.0 kips on the second benchmark problem (as shown in the figure).
• While holding these forces constant, run a series of load cases varying the axial force from 0 kips to 450 kips in increments of 50 kips (a total of 10 load cases to run) for the first benchmark problem and from 0 kips to 200 kips in increments of 20 kips (a total of 11 load cases).
• Repeat this for a 1, 10, and 20 element model for each of the two benchmark problems.

your final output
1. A table for each for the three models showing the load case, ?max, Mmax, both from the computer solutions and the exact, closed form solution, and the percent difference between the solutions (the solutions should agree within 3% for moment and 5% for deflection per the article).
2. Plots of P vs. ? and M vs. ? from your computer results for each of the three models...
