Design Example 



11. Figure Al shows an example of the SUMMARY screen output file 

 called CAUD.PRN for the program default design values. The default values are 

 from the 1986 Crescent City rehabilitation. Note that the design factor of 

 safety is not conservative, even though there is no reduction in the strength 

 to account for fatigue.

12. Figures A2 through A5 show plots for this example. Note that the 

 design nomograph shown in Figure A4 contains two solid curves and a dotted 

 line. The solid curve increasing exponentially up to the right is the 

 hydrodynamic stability curve based on the Hudson equation. Every point (H,W) 

 to the right of this curve is hydrodynamically unstable, while those points 

 to the left are stable. The solid curve sloping gently down to the right is 

 the structural strength curve. Every point (H,W) above the strength curve
