Example: Polygon friction zone option

 

The following example demonstrates the input format for the m-smac polygon friction zone option. (The input cards are taken from the m-smac input file ADVSAMP2.Si5 which is contained in the project file ADVSAMP2.prj). In this example, the polygon friction zone is a high friction zone located in the 1st quadrant.

 

The following are the card inputs for the polygon friction zone option:

 1.      11.     1.00                                                          30

 546.    186.    362.4   198.    283.    228.    224.    271.               0  31    

 188.    311.    151.    396.    130.    540.    116.    708.               1  31    

 99.     756.    540.    756.    546.    186.                               2  31    

 

The following is an echo of the card inputs for the polygon friction zone option:

The same inputs for the polygon friction zone option also could be entered in units of feet as follows:

(note that field 9 of card 30 is set=1.0)

 

 1.      11.     1.00                                            1.0           30

 45.5    15.5    30.2    16.50   23.6    19.     18.7    22.6               0  31    

 15.7    25.9    12.6    33.     10.8    45.     9.7     59.                1  31    

 8.25    63.     45.     63.     45.5    15.5                               2  31
