Area loads are finally coming to Tribby3d!

Column force calculations are finally coming to Tribby3d!

Column point loads can be calculated by multiplying the column’s tributary area with applicable area loads. For some structures, several area loads might overlap with the same column’s tributary area. Then the loading zones must be intersected with the tributary area to find out how much each area load contributes with. When this has been found, then the area segments can be multiplied with their corresponding pressure load (kN/m2). This process is very time-consuming to carry out manually. Using Tribby3d, this can be done in a second!

See below for details of how it works:

Using the cursor it is possible to select a column so its details can be viewed in the side panel.

In the panel you can see the total tributary area of the column (312.5 m2 in the example). Pay attention to the two hatched areas that overlaps with the trib area – these are two different loading zones!

Tribby3d calculates that Loading zone 1 contributes with 243.75 m2 (making up 78% of the total area), and that Loading zone 2 contributes with 68.75 m2 (making up 22% of the total area).

When this information is known, the areas can be multiplied with their corresponding area loads (kN/m2) to compute the total column force!
