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.
