2.16 Loads

It is possible to define a polygon load with variable ordinates to
represent dam or embankment loads, Figure B-27. |

It is possible to define a line moment to represent moments from
walls or line supports, Figure B-27. |

Point load never applied in realty. If a point load represents a
column load on a mesh of refine finite elements, the moment under
the column will be higher than the real moment. To take the effect
of the load distribution through the slab thickness, the column load
must be distributed outward at 45 [°] from the column face until
reaching the center line of the slab. Now, it is possible to
overcome this problem by converting the point load to an equivalent
uniform load over an appropriate area, Figure B-28. |
